OPERATION (‘HL’ Model) 12A
Never
commence work until the daily service checks have been
carried out.
Only
tip or discharge the skip or raise the scissors on level ground.
The hydraulic system control valve and operating levers are mounted
on top of the hydraulic tank on the left-hand side of the machine.
The inner lever controls the scissor operation whilst the outer lever
controls the skip tipping functions, the function of each lever is
indicated on the decal on the rear of the valve mounting plate.
The operating levers have three positions, forwards for ‘Scissor Lift’
or ‘Skip Tip’, centre for ‘Neutral’ or ‘Hold’ and rearwards for ‘Scissor
Lower’ or ‘Skip Return’.
The hydraulics will not operate until the engine is running, although
it is possible to lower a raised skip or scissors without engine power
by moving the operating levers to the ‘Dump’ or ‘Lower’ positions.
For this reason the machine should not be left unattended with either
the skip or scissors raised. Refer to the Honda HP500H Operators
Handbook for instructions on starting the engine.
With the engine running and the engine speed set to fast idle, refer to
the decal on the rear of the valve mounting plate and identify the
lever controlling the function required, slowly push the lever
forwards. The rate of oil delivered to the skip tipping or scissor ram
and therefore the speed at which the skip tips or the scissors lift is
proportional both to the distance the lever is moved and the speed at
which the engine is set.
Holding the lever forwards until the skip or scissors reaches the
maximum travel of the ram will cause the relief valve located in the
control valve to ‘blow off’ allowing the oil to return to tank. Do not
hold the lever forward when the ‘relief valve’ blows, this will cause
the hydraulic oil temperature to increase and may cause damage to
components. Once the ram reaches the end of its travel release the
lever to the neutral or hold position.
Releasing the operating lever will allow it to automatically return to
neutral position and movement of the skip or scissors will stop, even
if the ram has not reached the full extent of its travel, or the skip is
