4.2 Cleaning Plate
Clean plate after use to remove dirt, stones, and mud caught under the
engine console. If plate is being used in a dusty area, check engine
cylinder cooling fins for heavy dirt accumulation. Keep engine cylinder
fins clean to prevent engine from overheating.
4.3 Drive Belt
See Graphic: wc_gr000077
On new machines or after installing a new belt, check belt tension after
first 20 hours of operation. Check and adjust belt every 50 hours
thereafter.
To change the belt:
4.3.1 Remove the beltguard and remove the four hex nuts (a) holding pulley
halves (b) together. Remove outer pulley half and remove belt.
4.3.2 Install new belt on pulley and secure pulley halves together with hex
nuts. Adjust tension on belt by adding or removing spacers (c)
between pulley halves. The fewer spacers used between pulley
halves, the tighter the belt will be. Three spacers with new Wacker
belts should provide the correct tension. Belt deflection should be 6–
10 mm, checked half way between the clutch pulley and the exciter
pulley (d). Place unused spacers on outside of pulley.
4.3.3 Replace beltguard.
