Blade Wheel Belts

1.

Check the blade wheel belts for wear every 50 hours of operation. Replace as needed.

2.

Periodically check all belts for wear. Replace any damaged or worn belts as needed.

4.9

Brake Pads Adjustment ( Gas / Diesel Sawmills Only )

Check the brake pads for wear every 200 hours of operation. Replace if damaged
or worn.

Adjust the brake pads if the blade does not stop quickly, unusual sounds occur when the
brake is applied, or a sudden change is noticed in the clutch/brake lever position when
the clutch is disengaged.

WARNING!

Do not for any reason adjust the brake pads

with the engine running. Doing so may result in serious
injury.

Open the blade housing cover.

See Figure 4-4.

Loosen the locking bolts shown below.Adjust the brake pads so the

blade stops no more than 10 seconds after disengaging. The brake pads should enter the
grooves in the drive pulley when the brake is applied. If they are not, it can lead to their
