Operating Instructions, Form No. 1000090, Back sheet 1 of 6
WARNING: To help prevent personal injury,
HYDRAULIC HOSE
Before operating the pump, all hose connections must be tightened with the proper tools. Do not overtighten.
Connections should only be tightened securely and leak-free. Overtightening can cause premature thread failure
or high pressure fittings to split at pressures lower than their rated capacities.
Always shut off the electric motor before breaking any connections in the system.
Should a hydraulic hose ever rupture, burst, or need to be disconnected, immediately shut off the pump. Never
attempt to grasp a leaking pressurized hose with your hands. The force of escaping hydraulic fluid could cause
serious injury.
Do not subject the hose to potential hazard such as fire, sharp surfaces, extreme heat or cold, or heavy impact. Do
not let the hose kink, twist, curl or bend so tightly that oil flow within the hose is blocked or reduced. Periodically
inspect the hose for wear, because any of these conditions can damage the hose.
Do not use the hose to move attached equipment. Stress can damage the hose, causing personal injury.
Hose material and coupler seals must be compatible with the hydraulic fluid used. Hoses also must not come in
contact with corrosive materials such as creosote-impregnated objects and some paints. Consult the manufacturer
before painting a hose. Never paint the couplers. Hose deterioration due to corrosive materials can result in
personal injury.
PUMP
Do not exceed the PSI hydraulic pressure rating noted on the pump nameplate or tamper with the internal high
pressure relief valve. Creating pressure beyond rated capacities can result in personal injury.
Before replenishing the oil level, retract the system to prevent overfilling the pump reservoir. An overfill can cause
personal injury due to excess reservoir pressure created when the wrenches are retracted.
POWER SUPPLY
Never use an ungrounded power supply with this unit.
The pump must be compatible with existing line voltage.
Disconnect the pump from the power supply when performing maintenance or repair on the unit.
If the unit's power supply is damaged or the inner wiring is exposed in any way, replace immediately.
Any electrical work must be done by a qualified electrician.
If the power cord is damaged or wiring is exposed, replace or repair immediately.
Changing the voltage on the jet motor (single, or three phase) is a complicated and, if not done correctly,
dangerous procedure. Consult the pump manufacturer's Technical Services Department for specific information
before attempting any rewiring. Rewiring voids CSA approval.
All voltages must be wired for CW rotation when viewed from the lead end (top) of the motor.
Check the total amperage draw for the electrical circuit you will be using. (For example: Do not plug a motor or
motors that may draw 25 amps into a 20 amp fused electrical circuit.)
Do not attempt to increase the powerline capacity by replacing a fuse with another fuse of higher value.
Overheating of the powerline and the possibility of a fire will result.
To rewire a motor from one voltage to another or when a flow control valve is changed between manual and
solenoid, consult the electrical schematic in the pump's parts list.
Circuit Breakers:
Universal Motor: Move motor switch to OFF and control valve to neutral. Let motor cool or wait until power is
restored. Reset circuit breaker switch in power panel. (The pump motor doesn't have a circuit breaker.)
Single-phase Motor: Thermal overload switch will break circuit to the motor. Move motor switch to OFF and control
valve to neutral. Allow motor to cool before switching on again, or wait until power is restored.
Three-phase Motor: A magnetic starter switch breaks circuit to the motor. Move the motor switch to OFF and
control valve to neutral. Remove the cover on motor control box. Let the motor cool or wail until power is restored.
One of three reset buttons must be pushed in to reset motor. Replace cover.
SAFETY PRECAUTIONS
If motor stops due to an overload or power outage,
