Maintenance
Solution Pump
1. Check the crankcase oil level daily to assure the
proper level. Use the illustration as a guide when
checking the oil level. If the level has dropped,
check for the source of leakage and repair.
2. Remove yellow filler cap with attached dipstick. Oil
level should be between marks on the dipstick or
use the sight glass located on the non-shaft side of
the pump.
3. Change the crankcase oil with GP Pump Crank-
case Oil, after the first 50 hours of operation.
Drain and refill the crankcase oil with GP Pump
Crankcase Oil every 500 hours thereafter.
Solution pump oil capacity is approximately 14.0
ounces.
Vacuum Inlet Filter (in Waste Tank)
1. The vacuum filter in the waste tank should be
removed and cleaned daily. If this is done, the filter
will last for a long period of time.
Vacuum Relief Valve
While the unit is running at full RPM, block the air flow
at the vacuum inlet connection and read the vacuum
gauge. If adjustment is required, shut the unit down and
adjust the vacuum relief valve locking nut tension. Start
your unit and read the vacuum gauge. Repeat this
process until the relief valve opens at 13" Hg.
Vacuum Pump Drive Belts
To tighten the vacuum pump belts:
1. Loosen the four nuts which hold the vacuum pump
mount in place.
2. Turn the adjusting bolts until the proper belt tension
is achieved (1/2” deflection in the center of the belt,
halfway between the pulleys).
NOTE: When adjusting belt tension, make certain
that the engine shaft and vacuum pump shaft remain
parallel, and the belt tension is equal throughout the
belt width.
3. After adjusting, re-tighten the four nuts which hold
the vacuum pump mount in position. Check belt
alignment with straight-edge.
4. Check for pulley groove wear, clean belts and pul-
ley grooves, check for worn belts, proper belt ten-
sion, and pulley alignment after the first 25 hours
and then again at 100 hours.
