Electrical Power Cables
You could be electrocuted or badly burned if you get
the machine or its attachments too close to electrical
power cables.
You are strongly advised to make sure that the safety
arrangements on site comply with the local laws and
regulations concerning work near electric power lines.
Before you start using the machine, check with your
electricity supplier if there are any buried power
cables on the site.
There is a minimum clearance required for working
beneath overhead power cables. You must obtain
details from your local electricity supplier.

Control lever/switch action may vary on machines,
instructional labels near the levers/switches show by
symbols, which levers/switches cause what actions.
Before operating control levers/switches check the
instructional label to make sure you select the desired
action.

All levers move forward and back. The levers are spring-
loaded to their central hold positions. The speed of
movement of the associated hydraulic rams depends on
how far you move a lever - the further you move the lever,
the faster the ram action.
The rams will stay in any position until you move them with
the levers. (The mast descends by gravity, at a speed
which is controlled by a flow regulator in the hydraulic
circuit).
The following pages describe the operation of the various
control patterns.
