ATTEMP TO REPAIR, CONTACT W. CHRISTIE (INDUSTRIAL) LTD
IMMEDIATELY.
Before using the power pack electric unit ensure:-
1. The operating and safety instructions are read and understood.
2. The relief valve, located on the side of the unit is fully unwound (anti-clockwise)
3. Tank is filled with oil (Tellus 32 or equivalent).
4. Electric power supply is correct (110V or 240V).
5. Couplings are clean and fully engaged.
6. Connect hoses to the hydraulic tooling to be operated (see relevant operating instructions).
7. Start the pump running by pressing the ‘on’ button on the back of the control panel.
8. Depress the white button on the hand pendant.
9. Slowly rotate the relief valve, cylinder will extend.
Note: If cylinder does not extend, depress the black pendant button. Hydraulic pressure will register on
the gauge
10. Adjust the hydraulic pressure to the required setting using the relief valve on the outside of the
unit.
11. With pressure set, the power pack is now ready for use.
Note: This is a double acting pump unit, depressing the pendant control buttons will extend or retract a
cylinder. Which button extends and which button retracts is dependant on hose orientation.

SAFETY
1. The incorrect use of hydraulic equipment is dangerous. Ensure that personnel familiarise
themselves with the operating instructions.
2. Operating personnel should be safely and correctly attired i.e. safety glasses, safety boots,
industrial gloves and overalls.
3. If more than one engineer is involved in the operation of torque machinery, good communication
must be established to prevent accidents or misunderstandings.
4. Do not use electrical cables to tow the power pack.
5. NEVER exceed the maximum working pressure of hydraulic equipment.
6. Before use check pneumatic and hydraulic hoses are not cut, split, kinked or damaged. If in doubt
do not use.
7. Do not hold the hoses when they are pressurised, especially on the swagings. Hose failure may
lead to serious injury.
8. If any leaks are detected whilst the pump is in operation, stop using it immediately. Contact
W. Christie (Industrial) Ltd for guidance.
9. Take care not to stand on or run over hydraulic hoses or air lines. To minimise danger ensure that
these lines are not run across walkways, ladders, roadways and doorways and that people likely to
pass through the working area are aware of the danger.
10. Maintenance guidelines should be strictly adhered to, poor equipment may lead to component
failure and injury.
11. NEVER pressurise a hose or cylinder leaving the coupling at the other end disconnected. If this
coupling fails serious or fatal injury may result.
12. The pump unit contains aluminium and magnesium; this makes it unsuitable for use in certain
industries i.e. mining and petrochemical. For guidance contact W. Christie (Industrial) Ltd.
13. A power pack should never be used without a motor silencer fitted, noise may cause damage to
hearing.
14. No work should be undertaken by personnel unfamiliar with the hydraulic system. In the event of
the breakdown, contact W. Christie (Industrial) Ltd.
