Safety Precautions Continued
Pump
• Do not exceed the 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.
• The load must be under operator control at all times.
• Do not connect pump to hydraulic system powered by another pump.
Power Supply
• Electrical work must be performed and tested by a qualified electrician per local directives
and standards.
• Disconnect the pump from the power supply and relieve pressure before removing the
motor case cover or performing maintenance or repair.
• Check the total amperage draw for the electrical circuit you will be using. For example: Do
not connect a pump that may draw 25 amps to a 20 amp fused electrical circuit.
• Never use an ungrounded power supply with this unit.
• Changing the voltage is an involved and, if incorrectly performed, hazardous procedure.
Consult the manufacturer for specific information before attempting rewiring.
• Wire pump motors for counterclockwise rotation when viewed from the shaft end of the
motor.
• Do not attempt to increase the power line capacity by replacing a fuse with another fuse of
higher value. Overheating the power line may result in fire.
• Exposing electric pumps to rain or water could result in an electrical hazard.
• Avoid conditions that can cause damage to the power cord, such as abrasion, crushing,
sharp cutting edges, or corrosive environment. Damage to the power cord can cause an
electrical hazard.
Circuit Breakers
: If motor stops due to an overload or power outage:
WARNING
• 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.
