MAINTENANCE TIPS
Preventative maintenance is the key to smoothly operating equipment, as well as keeping the user’s liability to a minimum. Equipment needs to be inspected at regular intervals. Defective components must be replaced immediately. Improperly working equipment must be kept out of use until it is repaired. Ensure that any person(s) making adjustments or performing maintenance or repair of any kind is qualified to do so.
AFTER EACH USE (DAILY)
Clean and inspect, following these steps:
# Turn off the treadmill with the ON / OFF switch, then unplug the power cord at the wall outlet.
# Wipe down the running belt, deck, motor cover, and console casing with a damp cloth. Never use solvents, as they can cause damage to the treadmill.
# Inspect the power cord. If the power cord is damaged, contact Customer Technical Support.
# Make sure the power cord is not underneath the treadmill or in any other area where it can become pinched or cut.
# Check the tension and alignment of the running belt. Make sure that the treadmill belt will not damage any other components on the treadmill by being misaligned.
# If any labels are damaged or illegible, contact Customer Technical Support for replacements.
EVERY WEEK (WEEKLY)
Clean underneath the treadmill following these steps:
# Turn off the treadmill with the ON / OFF switch, then unplug the power cord at the wall outlet.
# Fold the treadmill into the upright position, making sure that the lock latch is secured.
# Move the treadmill to a remote location.
# Wipe or vacuum any dust particles or other objects that may have accumulated underneath the treadmill.
# Return the treadmill to its previous position.
EVERY MONTH - IMPORTANT
# Turn off the treadmill with the ON / OFF switch, then unplug the power cord at the wall outlet.
# Inspect all assembly bolts of the machine for proper tightness.
# Remove the motor cover. Wait until ALL display screens turn off.
# Clean the motor and lower board area to eliminate any lint or dust particles that may have accumulated. Failure to do
so may result in premature failure of key electrical components.
# Vacuum and wipe down the belt with a damp cloth. Vacuum any black / white particles that may accumulate around the unit. These particles may accumulate from normal treadmill use.

EVERY 6 MONTHS OR 150 MILES
It is necessary to lubricate your treadmill running deck every six months or 150 miles (240 kilometers) to maintain optimal performance. Once the treadmill reaches 150 miles (240 kilometers), the console will display the message “LUBE” or
“LUBE BELT”. The treadmill will not operate while the message is showing. Hold ‘STOP’ for 5 seconds to suspend message for 5 miles.
Your treadmill came with a bottle of lubricant which can be used for two applications.
# Turn off the treadmill with the on/off switch, then unplug the power cord at the wall outlet.
# Loosen both the rear roller bolts. (for best results, place two removable marks on both sides of the frame and note roller position). Once the belt is loosened, take the bottle of  lubricant and apply it to the entire top surface of the running deck. Tighten both rear roller bolts (matching up the marks for proper position) to original position. After you have applied lubricant, plug in the power cord, insert the safety key, start the treadmill and walk on the belt for two minutes to spread the lubricant.
# Lubricate the air shocks with Teflon based spray.
# Once lubrication is complete, reset the console by pressing and holding ‘STOP’ and ‘SPEED +’ buttons for 5 seconds.

TENSIONING & CENTERING THE RUNNING BELT

If you can feel a slipping sensation when running on the treadmill, the running belt must be tightened. In most cases, the belt has stretched from use, causing the belt to slip. This is a normal and common adjustment. To eliminate this slipping, turn the treadmill off and tension both the rear roller bolts using the supplied Allen wrench, turning them ¼ turn to the right as shown. Turn the treadmill on and check for slipping. Repeat if necessary, but never turn the roller bolts more than ¼ turn at a time. Belt is properly tensioned when the slipping sensation is gone.

The running belt has been properly adjusted at the factory before it was shipped. At times the belt can move off-center during shipment. Before operating the treadmill, make sure the belt is centered and remains centered to maintain smooth operation.

If the running belt is too far to the right side: With the treadmill running at 1 mph, turn the left adjustment bolt counter-clockwise1/4  turn at a time (using the supplied Allen wrench). Check the belt alignment. Allow belt to run a full cycle to gauge if more adjustment is needed. Repeat if necessary, until the belt remains centered during use.

If the running belt is too far to the left side: With the treadmill

running at 1 mph, turn the right adjustment bolt counter-clockwise 1/4 turn at a time (using the supplied Allen wrench). Check the belt alignment. Allow belt to run a full cycle to gauge if more adjustment is needed. Repeat if necessary, until the belt remains centered during use.

2. Turn the program knob (1) click clockwise from the start position. The hot water solenoid will activate and hot water should enter through the detergent compartment.
3. Turn the program knob (2) clicks from the start position. The bleach water solenoid will activate and cold water should enter through the bleach compartment.
4. Turn the program knob (3) clicks from the start position. The bleach and the wash water solenoids will activate and cold water should enter through the softener compartment.
5. Turn the program knob (4) clicks from the start position. The door lock solenoid will activate.
6. Turn the program knob (5) clicks from the start position. The door lock solenoid will deactivate and the loading door can be opened.
7. Turn the program knob (6) clicks from the start position. The washer will fill and tumble.
8. Turn the program knob (7) clicks from the start position. The washer will fill and spin (leakage test).
9. Turn the program knob (8) clicks from the start position. The drain pump and door lock solenoid will activate and the washer will operate in high spin. Safety warning: if power is removed during this test, the door can be opened. To prevent injury, do not put your hands inside when the tub is rotating.
10. Turn the program knob (9) clicks from the start position. The control will signal the last error code.
Quick Check
If there is no error displayed and the washer momentarily starts then turns back off:
1. Listen for a relay closure inside the Speed Control Board shortly after the Start key is pressed. If this happens, the motor control has power.
2. Check the 5-pin connector wiring between the Console Control and the Speed Control Board.

In the Better models line, the failure codes will appear in the display as an E followed by two numbers, a number and a letter, or two letters. The control will beep and the door lock, wash, rinse, final spin and control indicator lights will flash.
Example: E14. To stop the flashing, the customer may touch the Pause/Cancel button. The error code remains stored in the control but once the problem is corrected, it does not effect the operation of the washer. If the failure is something that the customer can correct (such as the water faucets being turned off), the washer will operate normally the next time it is started.
In the Good models line, the control signals the failure code by flashing the five indicator lights of door lock, wash, rinse, final spin and control for the first number or letter after the E and the start indicator light for the second number or letter after the E. When a failure occurs, the washer stops or pauses and the control beeps and flashes the five indicator lights to tell the customer that a failure has occurred. To stop the flashing and beeping, the customer may touch the Pause/Cancel button. The error code remains stored in the control but once the problem is corrected, it does not effect the operation of the washer.

Bladez ION 7.9T: TROUBLESHOOTING 

Tools need: Multimeter, phillips screwdriver,
When unit turns on, no power on the console and on/off switch does not light up.

1. Check the wall AC outlet for power, please make sure to switch multimeter to read AC output before proceeding to plug probes to the wall outlet as shown. It should read approximately 120-130V. If you get zero or very low reading, you get a bad wall outlet. Otherwise, proceed to step 2. If you don’t have multimeter, plug any working appliance that you know to see whether the outlet is working fine.

2. If AC outlet is fine, then check on/off switch. Pull out the cables on the top of the on/off switch and place probes on the switch as shown to read the AC output. The reading should be around 120-130V. If there is none or very low reading, you get a faulty switch. Please call Bladez for on/off switch replacement part. Otherwise, proceed to step 3.

If the console has no power, but the on/off switch light up.

3. Check the cable connections on the back of the console a. Remove screws to pull the rear console cover b. Verify all wires are secure and attached in the correct position as shown. Verify that there aren’t any pinches or cuts in any of the wires in particular the main cable where the uprights are joined with the base frame or where the console joins with the uprights.

4. Turn unit off, set multimeter to read OHM. Then place probes on both legs of the circuit breaker, reading should be around 0.3-0.5Ω. If there is zero or very low reading, replace circuit breaker. Otherwise, go to next step.

6. Power off the unit, pull out cables M+ and M- (motor cables) from the Lower control board. Then place probes on the motor connects on the board as shown, make sure the multimeter is set to read DC output before restarting the treadmill. Then press quick start to start to unit and you should read 26-30V before the error code E1 appears on the treadmill console. If you get zero or very low reading, then you may have a defective lower control board.

Check whether the fuse on the lower board is defective before replacing the board. Make sure the unit is power off, turn the voltmeter to read continuity as shown. You will hear a beep sound if the fuse is good or no beep if the fuse is bad.

E1-Message

Lift up the front motor cover by removing 4 screws, then check the alignment of the speed sensor as shown below.

Sony Handycam - DCR-SR42 - Disassembling - How to remove and Replace the Hard disk drive

Sony Handycam - DCR-SR42

Hard drive Replacement Procedure 

Remove the battery, and use the Phillips #00 precision screwdriver to then remove the three 3mm Phillips #00 screws under the battery. Wait 1 hour after removing the battery before continuing to disassemble the camera.

Remove the three 3mm #00 Phillips screws on the bottom of the camera.

Remove the three 3mm Phillips #00 screws on the side of the camera. Remove the 4mm Phillips #00 screw under the AV port cover.

Gently pull the black plastic hard drive cover away from the body of the camera. This will expose the hard drive. Even with all the screws removed, this part will require some force to remove.

Lift the hard drive out of the camera by grasping the grey rubber mounting brackets and pulling them upwards. The hard drive is attached to the flex cable. Remove the hard drive slowly to prevent the flex cable from being damaged.

Remove the rubber mounting brackets by pulling them off the hard drive.

Carefully unplug the flex cable from the hard drive.
