1.When using, do not permit any person stand at the oil output in order to avoid personal injury and
equipment damage. Please put the pump far away from the fire.
2.Make sure that the hose and quick coupler be connected before building up the pressure in order to
avoid hydraulic fluid spurting out to cause personal injury.
3.The maximum operating pressure of this pump is 700Bar(10,000Psi),WREN has set up the pressure to
700Bar before selling this pump. Please do not adjust to a pressure higher than the maximum pressure
whichWREN has not set.
4.If this pump is used for operating other equipments, make sure the maximum operating pressure of the
equipments will be less than 700Bar. Please adjust the pressure to which the equipment need, or else the
equipment would be damaged.(Referrence content 5)
5.Make sure the power of the pump is shut off before repairing it.
6.Please shut off the switch before starting power; if the switch is on, the pressure may increase.
7.Make sure the equipment be connected with ground to avoid electric shock.
8.Do not start the pump without oil in tank.
9.Please do not change any part of the pump; if it must be changed, please inform WREN or Wren's agent
for help. Without allowance of WREN or its agent, any refit of it will be out of our warranty Range.
10.Please do not fill the pump reservoir with too much oil, otherwise, the pressure of the reservoir will
increase and the oil will spill over, so the reservoir will be broken and the environment will be polluted.
11.When the pump works,the pressure may be increased with the returning oil.If the oil filler cop is opened
at the moment, this may cause the injury.
12.Make sure the quick coupler is tightened; if the quick coupler is not tightened enough, the equipment
will not work normally; if it is a synchronic system, the problem may cause one or several pieces of
equipment out of order and the quick coupler may be broken and it may cause personal injury or equipment
damage.
13.Make sure to reep the pump in cleaning.
14.Please stand away from the position where the hydraulic oil may be spurt out; hydraulic
oil may penetrate your hand and hurt you.
15.If the hydraulic oil splashed in your eyes, please immediately wash your eyes about 15
minutes with clean water, then you must go to hospital for help right now.
