Always check the engine for proper level of engine oil. The
engine warranty is VOID if run without oil. Check the oil level
daily and change the oil weekly .
B. Clutch: A few drops of lightweight oil occasionally squirted
between the clutch mechanism cover and the floating cone will
help keep the mechanism free of debris and is the only clutch
maintenance required
C. Pillow Block Bearings: After every 40 hours of
operation, remove the belt guard (Item B, Figure 18) and
grease each bearing (Item D) with quality grade multi­purpose grease.

V-Belt Tensioning

T o tension the V -Belt (Item A, Figure 19)perform the follo wing:

1. Remove the belt guard (Item B).

2. Loosen the four (4) bolts (Item C) and slide the pillow
block (Item D) away from or toward the engine to tighten or
loosen the V -Belt until proper tension is achieved.

Cleaning

Clean the machine following each screeding operation before
concrete is allowed to dry on the machine. This is especially
important on the clamping stud threads. Keeping the belt
guard in place during operation not only provides a measure
of safety , b ut also helps to protect the eccentric, centrifugal
clutch, and belt from foreign matter .

General

Check for broken or missing componenst before each use.
Check all bolts for tightness bef ore each use. Tighten if
necessary .

MAINTENANCE SCHEDULE
Daily (8-10 Hours)

1. Check the oil level in the engine crankcase; fill as necessary.

2. Check V-belt.

Weekly (50-60 Hours)

1. Check the engine air filter and replace as necessary .

NOTE: Before retightening the pillow block bolts, be sure to
