Note: The Pulley will move slightly onto the Bushing when tightening the Bolts. You may need to compensate for this
movement when positioning the Bushing on the Shaft.
f)
Slowly tighten the Bushing Retaining Bolts evenly and alternately (1/4 to 1/2 turn). The Bolts only need to be snug.
Do not over tighten.
g) Recheck the alignment and adjust as needed.
5.
Retighten the Tensioner Bolt if you loosened it for alignment.
6.
Place a Straightedge along the Belt (over the Clutch and Sheave) and push
down firmly on the Belt to measure the deflection from the Straightedge to
the Belt with a tape measure (Figure 47).
7.
The measurement should be approximately 3/8" with approximately 10
pounds of force applied to it.
8.
If the measurement is not correct, tighten or loosen the Tensioner Bolt as
needed (Figure 43).
9.
Repeat steps 5 through 7 until the proper Belt tension is achieved.
10. When the Belt is properly tensioned, ensure that the four Engine Bolts are
completely tightened.
11. Reinstall the Belt Guard.
Note: Check and re-tighten the Drive Belt, if necessary, after an initial break-in
period of one hour.
VISUAL inspection of the Chipper Knife (before each use)
Routinely check the chipper knife for sharpness. Using a dull knife will decrease performance and cause excessive vibration that
will cause damage to the DR SELF-FEEDING WOOD CHIPPER.
Tools Needed:
•
7/16" Wrench
1.
Loosen the Locknuts that secure the Front Access Cover (Figure 48). Move
the Cover over to align the larger portion of the hole with the Locknuts and
remove the Cover.
2.
Rotate the Flywheel with a long stick until the Knife is visible.
3.
If the Knife has visible nicks or damage it must be sharpened or replaced
(see "Removing and Replacing the Chipper Knife" in this chapter).
4.
If the Knife does not appear to have any damage, replace the Access Cover
and tighten the Locknuts.
