3.3 Starting the power pack (see fig. 2)
Prior to starting the power pack, check that the hand control pendant is turned 'off.' Set the throttle
control lever to half of full throttle (2). Turn 'on' the battery isolator (1). Push the engine start push
button (4) until the engine starts.
Allow the engine to reach working temperature by running it at 1500 r.p.m. under zero load for
10-15 minutes. Check all gauges and diagnostic lights for correct function of unit (diagnostic lights
should be off.)
Notes:-
1. If any of the following L.E.D.'s (7, 8, 9 or 10) are 'on' when the isolator switch (1) is turned 'on,'
the power pack will not start. Rectify problem immediately.
2. If L.E.D. (12) is on, the power pack will start but the pendant will be ‘dead’ until the hydraulic
oil warm up procedure is carried out.
3.3.1 Hydraulic Oil Warm-up Procedure
If the hydraulic oil temperature is less than +25ºC, L.E.D. (12) will be on and the oil will require
warming prior to using the hammer.
The hand control pendant will be ‘dead’ for as long as L.E.D. (12) is on.
To warm the oil:-
a) Run the engine at 1800 r.p.m.
b) Turn the ‘warm-up/run’ selector switch (13) to ‘warm-up’. (The engine should go under load
and the high pressure gauge (5) should read approx. 200 bar).
c) Leave the pack in this condition until the L.E.D. (12) goes off. (The engine should come off
load at the same time the L.E.D. goes out and gauge (5) return to zero bar).
d) Turn the ‘warm-up/run’ selector switch (13) to ‘run’. The power pack is now ready for use.
3.4 Using the hammer
3.4.1 Installing hammer on the pile
The hammer must be sat correctly on the pile to avoid hammer or pile damage. The pile tops should
be as level and square cut as possible. The hammer anvil must be in good condition.
Lift the hammer onto the pile(s) to be driven. Lower the hammer down until the handling slings
lose their tension. At this point, the anvil should be seated correctly i.e. the rubber ring around the
anvil should be compressed between the casing and the anvil. If it is not and there is a gap here,
re-site the hammer.
Note:
Before using the hammer (and particularly after transportation) check
that the dolly is fitted correctly in the anvil.
