Pivot Assembly
Grease with a pressure gun as required.
Lubrication
Quick Disconnect Lock
A small amount of any lightweight oil should be used on the
locking mechanism to help keep concrete from sticking and
also to lubricate the locking pin and spring.

V-Belt Tension
The belt can be tightened by rotating the eccentric
countershaft assembly clockwise. When the belts are
properly tensioned, they should deflect approximately 5 to
10mm when 5-10 pounds of force is applied centrally between
the pulleys. Lock the countershaft in place with the locking
screw and wing nut.
DO NOT
use gasoline as a cleaning solvent to avoid
creating the risk of fire or an explosion.
Engine Air Cleaner
1. Remove the air cleaner cover and foam filter element as
shown in Figure 26.
2. Tap the paper filter element (Figure 26) several times on
a hard surface to remove dirt, or blow compressed air
[not exceeding 30 psi (207 kPa, 2.1 kgf/cm
2
)] through the
filter element from the air cleaner case side.
NEVER
brush off dirt. Brushing will force dirt into the fibers.
Replace the paper filter element if it is excessively dirty.
3. Clean foam element in warm, soapy water or nonflam-
mable solvent. Rinse and dry thoroughly. Dip the element
in clean engine oil and completely squeeze out the
excess oil from the element before installing.
