FORCE BLOWER
DRIVE CHAIN REPLACEMENT
1.Wait for engine to cool and disconnect spark plug.
2.Place a block of wood, or another object that will support and steady the unit under the axle on the side of the machine you will be working on.
3.Remove the two screws (item 103) holding the chain guard (item 104) and then remove the chain guard.
4.Loosen the two nuts (item 98) holding the bearing (item 97).
5.Remove the retaining ring holding the wheel on and then slide the wheel off.
6.Replace the chain (item 105). Remove the old chain by walking it off the sprockets.
7.Position the bearing so that it applies the proper tension to the chain and tighten the nuts holding the bearing Note: DO NOT over tighten the chain, as this will cause premature failure. Likewise if the chain is too loose it will come off when the drive is engaged.
8.Reassemble the machine using steps
Loosen these
nuts
CLUTCH CABLE ADJUSTMENT
1.With the machine off, loosen the two nuts on the end of the clutch cable (item 111) going in to the transmission.
2.By moving the position up or down on the threads it will change the tension on the clutch lever (item 113). Note: Do not position it too high on the threads as this could cause the drive not to engage. Likewise, if it is placed too low the drive may stay permanently engaged. The optimum setting is to remove any slack in the clutch cable when disengaged. The travel of the clutch control will apply the correct spring force on the cone clutch. Once the desired position is in place tighten the nuts securely.
3.Start the machine and check the operation. If the drive cable is not engaging properly, shut the machine off and reposition the nuts on the cable to tighten the drive cable.

*Using compressed air, or a Backpack blower, you can loosen or free debris easily from the impeller and housing, which can cause wear and tear on the machine. You can manually remove debris by taking off the front housing. Note: Always disconnect the spark plug when servicing.
