SAFETY PRECAUTIONS

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:

If motor stops due to an overload or power outage,

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.
