GENERAL INSTRUCTIONS
CAUTION: Positive Displacement Pumps must have a
proper size and operable type of pressure regulating
valve or pressure relief valve piped into the discharge
line. This is mandatory to prevent damage to pump
and piping or possible injury to personnel. Do not
install any valves or shutoff devices in the by-pass
line from pressure regulator to tank or supply.
CAUTION: All pumps should be installed level.
For mobile applications the maximum angle of
intermittent operation should be no more than
5 degrees in any one direction.
CALIFORNIA PROPOSITION 65 WARNING:
This product and related accessories
contain chemicals known to the State of California
to cause cancer, birth defects or other reproductive
harm.
BELT DRIVE SEWER CLEANERS
With belt drives, pulley on both engine and pump should
be located as closely as possible to bearing to reduce
bearing and shaft bending loads.
NOTE: See Maintenance Chart for Belt Tension
Specifications in Sewer Cleaner “Operator’s Manual”.
Make sure that all bolts, nuts, set screws, and keys are
properly tightened.
STARTING PUMP
A. Before starting:
1. Read all instructions carefully.
2. Fill pump crankcase with recommended oil to level
mark on oil saber. Oil recommendations are covered
in lubrication section of pump instructions.
3. Replace all drain plugs in pump and piping.
4. Inspect tank to be sure that no foreign material is in
tank or suction line.
5. Fill tank at least half full or connect suction to
water supply. Open valve (if present) in suction line.
Avoid prolonged dry operation which may cause
excessive wear on cylinders and piston packing.
Be sure that an operating pressure gauge is
located in discharge line.
6. Make sure all valves,including spray gun or nozzles,
are open in discharge line. Spray gun may be
anchored to discharge back into tank.
7. Completely back off pressure adjusting screw on
pressure regulating valve.
B. Starting the Unit:
1. After starting, close discharge valve or spray gun
slowly while watching pressure gauge to make sure
relief valve or unloader is operating properly.
2. Adjust relief valve or unloader to desired pressure.
See regulator instructions.
3. Cycle nozzles or gun on and off to be sure that
pressure adjustment and regulator operation is
satisfactory.
NOTE: Nozzle capacity should not exceed 90% of pump
capacity for satisfactory regulator operation. AVOID
FREEZING by draining all water from pump and system
in cold weather.
