ASSEMBLY & ADJUSTMENTS

       

WARNING:

 Do not plug in or turn on the tool until it is fully assembled according to the instructions. Read 

through and become familiarized with the following procedures of handling and adjusting your miter saw. Failure 
to follow the safety instructions may result in serious personal injury. 

ADJUSTING THE DRIVE BELT

1. Unplug the tool from its power source. Loosen the 3 screws securing 

the drive belt housing cover (Fig. 17) to the drive belt housing. Remove 

the drive belt housing cover.

2. Using a 5mm hex wrench (not included), loosen, but do not remove, 

the 6 hex screws (Fig. 18) that secure the motor to the belt drive housing.

3. Using a 4mm hex wrench (not included), turn counterclockwise 

to loosen the set screw (Fig. 19 - 1) at the top of the of the belt drive 

housing. This will release the tension on the drive belt and allow for 

adjustments or replacements of the belt.

4. Re-seat the belt on the pulley, making sure the belt is properly 

seated in the grooves of both pulleys. Re-tighten the belt by turning 

the set screw (Fig. 19 - 1) clockwise. Re-tighten the 6 hex screws 

(Fig. 18).

5. Test belt tension by squeezing both sides of the belt. If properly 

adjusted, the belt should “give” between 1/16" - 1/8" (1.5mm - 3mm). 

Make sure that the belt grooves are properly seated in the pulleys.

6. Carefully reinstall the drive belt housing cover by tightening the 3 

screws (Fig. 17).

NOTE: 

Excessive tightness on the pulley belt will cause increased 

noise and motor overload. Premature failure will occur if the belt is 

too loose.

ADJUSTING THE FENCES

1. Loosen the fence adjustment knob (Fig. 20 - 2).

2. Adjust the fence as desired. The top portion of the fence (Fig. 20 - 1) 

can slide to the left and right, while the bottom portion of the fence (Fig. 

20 - 3) stays stationary.

3. Tighten the fence adjustment knob to lock the fence into place.

       

WARNING:

 To prevent serious injury, after making any adjustments to the cutting angle, make sure the 

both sides of the fence are clear of the blade's cutting path. With the power OFF, move the blade through its full 
range of motion to check this.
