STORAGE & MAINTENANCE

SPECIFIC MAINTENANCE:

EVAPORATIVE EMISSION COMPONENTS:
The unit you have purchased includes the following components that are
in compliance with ALL current California Air Resources Board Evapora-
tive Emission Standards;
1. Fuel Hose
2. Fuel Hose Fittings
These components should be inspected on a daily basis for cracks, leaks,
and abnormal wear. If cracking, leaks or abnormal wear has occurred, the
components should be replaced immediately.
ENGINE: The engine instruction manual accompanying your unit lists the
specific procedures for maintenance on the engine. Following the engine
manufacturer's recommendations will extend engine life.
PUMP: Change the pump oil after the first 50 hours of operation. After
initial change, the manufacturer recommends changing the oil every three
months or at 250 hour intervals. If oil appears dirty or milky, changes may
be required in greater frequency. Use SAE20 or 30 non-detergent pump
oil and fill only to the center of the oil sight glass. DO NOT overfill.
NOZZLE: Water flow through the spray nozzle will erode the orifice,
making it larger, resulting in a pressure loss. Nozzles should be replaced
whenever pressure is less than 85% of the maximum. The frequency of
replacement will depend upon such variables as mineral content in the
water and number of hours the nozzle is used.

MAINTENANCE-EVERY 3 MONTHS:

CHANGE WATER PUMP OIL: Ensure unit is off. Change the pump oil
after the first 50 hours of operation. After initial change, every 3 months or
500 hour intervals are recommended. If oil appears dirty or milky, chang-
es may be required in greater frequency. Use SAE20 or 30 non-detergent
pump oil and fill only to the center of the oil sight glass. DO NOT overfill.
REPLACE HIGH PRESSURE NOZZLE: Water flow through the spray
nozzle will erode the orifice, making it larger, resulting in a pressure loss.
Nozzles should be replaced whenever pressure is less than 85% of the
maximum. The frequency of replacement will depend upon such variables
as mineral content in the water and number of hours the nozzle is used.
MAINTENANCE-EVERY 3 MONTHS CONT.:
BELT INSPECTION (BELT DRIVE ONLY): Ensure unit is off and remove
the beltguards. Inspect the v-belt for wear and tightness. If the v-belt
needs to be replaced or tightened, follow the procedures listed below:
REPLACEMENT:
1. Loosen the four pump mounting bolts (A).
2. Loosen the two alignment nuts approximately one inch on the alignment
bolts (B1 & B2).
3. Slide the pump toward the engine to loosen belts.
4. Remove and replace belt.
TIGHTEN: (if v-belt was not replaced, you will need to loosen the nuts on
the alignment bolts B1 and B2 before proceeding.)
1. Tighten B2 alignment bolt. The pump will shift to the left until there is
tension on the belt. Then tighten B2 nut.
2. Tighten B1 alignment bolt, until sheaves are straight. (Use a straightedge
for alignment.)
