depending upon how it is used and operated. There-
fore, the recommended operating procedures con-
tained within this manual should be followed at all times
for maximum productivity.
As noted in the Alitec literature, the attachment requires
a minimum hydraulic supply of 25 gallons per minute
(90 liters per minute) at 2000psi.
IMPORTANT
■
Insufficient hydraulic power will result in poor
performance.
In attaching the planer to the skid steer, ensure that all
hydraulic hoses are coupled securely to the quick cou-
plers - 3 hoses (motor pressure, return, and casedrain).
IMPORTANT
■
Casedrain must be attached and hose pressure
must not exceed 15psi. Motor seal failure will occur
if the casedrain is not attached, if the hose is
crimped, or if hose pressure is excessive. All hoses
should be free of kinks, cuts, or abrasions for safe
operation.
When using a quick attachment hookup to the skid
steer. the locking pins on the loader arms should always
be engaged and secured.
■
Never open the hinge drum access cover used
for drum access during operation. The two klik pins
(see exploded diagram) should be checked to make
sure they are securely fastened before beginning
operation.
When engaging the hydraulic power to the attachment,
the drum should not be in contact with the surface to be
planed. Free rotation is required to prevent excess
pressure spikes upon startup. As is always the case,
the operator must always be seated in the host vehicle
upon startup.
Engage the hydraulic power and lower the planer
slowly. Actuate the bucket cylinder function for rollout
until the planer wheels come in contact with the planing
surface. Then set to desired depth. Before advancing
the host vehicle, allow the planer to operate until it
reaches the desired planing depth.
IMPORTANT
■
For proper operation, the majority of the weight
of the front of the skid steer should be placed upon
the planer with the loader arms fully lowered. The
transfer of skidsteer weight to the attachment
results in smoother, faster planing. The loader
arms should never be placed in the float condition;
because, excessive vibration will result.
With the rear gauge wheel(s) set for acceptable planing
depth, the bucket function should be used for lifting or
lowering during operation.
The drum rotation will stall when the load on the planer
is too high. This is most likely the result of excessive
ground speed. The hydraulic reliefs on board the skid
steer are designed to prevent damage to the hydraulic
system by diverting all flow from the planer motor. If this
occurs, stop or slightly reverse the forward drive of the
skid steer and slowly move forward.
IMPORTANT
■
The bucket cylinder function should never be
used to stop operation due to the existence of sec-
ondary reliefs on some skid steer bucket cylinders.
For maximum productivity, the planer should always be
operated at full engine throttle to ensure that full
hydraulic horsepower is available to the cutting drum.
Side Shift Operation
The two sideshift hoses, when connected to the auxil-
iary hydraulics of the skid steer, provide hydraulic power
necessary for sideshift operation. By actuating the
auxiliary circuit, the planer will shift on sideshift rod.
Hydraulic Tilt
To operate the hydraulic tilt, set the options toggle
switch located at the operator’s control panel to ‘tilt’, and
actuate the auxiliary circuit.
Hydraulic Depth Control
To operate the hydraulic depth control, set the options
toggle switch to ‘depth’ and actuate the auxiliary circuit
to achieve the desired depth.
IMPORTANT
■
All function adjustments must be done with
high flow hydraulics engaged.
Transporting
Roll the skid steer arms fully back and raise the planer
12 to 15” off the ground. Avoid excessive ground speed
and sudden meneuvers.
IMPORTANT
■
When transporting attachment make sure the
drum does not contact the ground as this may
cause the drum to turn resulting in damage to the
motor.
