Make sure that all the components are fit
for the intended use
.
Ensure there is sufficient oil capacity
in the pump reservoir to fully operate
the system to be used.
DO NOT exceed the rated pressure
of the pump or the rated capacity of
the system to be used. Under no
circumstances ever tamper with the
internal safety relief valve of the pump.
Keep hydraulic pumps away from
flames and direct heat.
Hydraulic pumps must only be serviced by
a qualified technician.
To protect your warranty, only use Hi-
Force’s hydraulic oil.
Immediately replace any worn or
damaged parts using genuine Hi-Force
parts only.
The system operating pressure must not
exceed the pressure rating of the lowest
component in the system. Where possible,
use a pressure gauge to monitor the
system.
Avoid damaging hydraulic hoses. Always
route hoses to ensure that they are free
from sharp bends and kinks. Using bent or
kinked hoses will cause severe back-
pressure and can also lead to failure of the
hose.
Always stand the pump on a stable
level surface during operation.
Never invert the pump or lay it on its
side either in use, during transportation or
in storage.
Inspect all hoses on a regular basis
for damage and wear. Do Not use
hoses that are frayed, abraded or leaking.
Never lift, pull or carry any hydraulic
pump or components by the hose or
hoses connected to them.
Do not handle a pressurized hydraulic
hose. Oil escaping under pressure from a
ruptured hose can penetrate the skin and
lead to a serious medical emergency and
in certain cases death. Should this incident
happen medical attention must be sought
immediately.
Never pressurize disconnected
couplings
Always operate the system under no load
condition prior to the actual lift to ensure
that no air is trapped in the hydraulic circuit.
Do not drop or place heavy objects on a
hydraulic hose as this will cause internal
damage to the hose which could result in
rupture when the hose is pressurized and
could result in serious damage to
components, and possible serious personal
injury to operating personnel.
Always isolate the pump from the
electrical supply when carrying out
any maintenance work or adjustments
to the pump.
Be aware of hot sufaces on the
motor of the electric pump. Do not
obstruct the free flow of cooling air around
the motor fan and casing.
