PORTO-SCREED PSH — MAINTENANCE
ALWAYS allow the engine to cool before
servicing. NEVER attempt any maintenance
work on a
hot!
engine.
Lubrication
A. Engine: Lubricate the engine-refer to the “Engine Manual”.
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 multi-
purpose grease.
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, but also helps to protect the eccentric, centrifugal
clutch, and belt from foreign matter.
V-Belt Tensioning
To tension the V -Belt (Item A, Figure 19)perform the following:
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.
NOTE: Before retightening the pillow block bolts, be sure to
align the eccentric assembly (Item E) perpendicular to the belt.
WARNING
Whenever assembling, lubricating, cleaning or adjusting any
part of the screed, make certain the engine is stopped with the
spark plug wire disconnected and secured away from contact
with the spark plug.
General
Check for broken or missing componenst before each use.
Check all bolts for tightness before each use. Tighten if
necessary.
