TENSIONING THE BELT PROCEDURE
Caution:
Over-tightening of the roller will severely shorten the life of the belt and may
cause further damage to other components.
Running Belt:
If when you plant your foot on the belt, you can feel a slipping sensation then
the belt has stretched and is slipping across the rollers. This is a normal and
common adjustment on a new treadmill. To eliminate this slipping, tension
both the rear rollers Allen bolts 1/4 TURN as shown above. Try the treadmill
again to check for slipping. Repeat if necessary, but NEVER TURN the roller
bolts more than 1/4 turn at a time.
Perfect Tension of Running Belt:
Perfect Tension of Running Belt:
0.9~1.1 lbs
0.9~1.1 lbs
Frequency: Every 1 months
6
Drive Belt:
If you have tensioned the running belt and are still experiencing a slipping,
adjust the tension screw. Then try the treadmill again to check for slipping.
7
DECK RE-WAXING PROCEDURE
Frequency: Every 1 month
Parts name: Silicon oil set
Parts number: SZTM74SOS
Price (USD): 0.6
Use time : 1
Procedure:
1. Loosen the tension bolts at both ends.
2. Pull the belt with your left hand and apply the silicon in the deck
with your right hand. (The volume of silicon applied is about
40ml)
3. Tighten the tension bolts.
4. Start the treadmill. Step on the treadmill belt to walk the silicon in.
Adjust the belt tension if necessary.
5. With the clamp-on meter, measure the current draw of the motor.
(Clamp on either the red or the black wire.) The current should
be less than 15Amps for 110V model. (less than 7.5Amps for
220V model.)
Caution:
If deck is not to periodical add the waxing, between the deck and running
belt will produce great friction make the deck and running belt to burn up and
cut down the motor life .
8
Use the
clamp-on meter (DC current-meter)
:
With the clamp-on meter, measure the current draw of the motor.
(Clamp on either the red or the black wire.) The current should
be less than 15Amps for 110V model. (less than 7.5Amps for
220V model.)
current limit :
9
CLEAN THE GROOVES PROCEDURE
Frequency: Every 3 months
Procedure:
1.Remove the drive belt and check the
grooves in belt for dirt or dust and clean it.
3Check the grooves in roller pulley for dirt or
dust and clean it.
If dirty grooves in the drive belt, motor and roller pulley, there will be noises
while running.
Caution:
2.Check the grooves in motor pulley for dirt
or dust and clean it
10
Use the carbon stick to clean the DC motor
Frequency: Every 3 month
Caution:
If the treadmill with DC motor makes noise or running speed isn’t stable. You
can use the carbon stick to clean the motor
Parts number : MTOOL- 042
1 Box – 10 pcs
Price : USD 28.5
11
Carbon stick use Step :
Step 1.
Take off the motor cover.
Step 2.
Take off the motor carbon brush cover.
Step 3.
Press “Start” key to run in the middle speed.
Step 4.
Put the carbon stick to clean the motor dust inside.
