Operating the Ice Resurfacer
7 - 6
Shaving or Cutting
Proceed from the storage area onto the ice (see Figure 7.4).
When starting the resurfacing pattern, it is recommended to start down the
center of the ice surface so the functions can be started and blade adjustments
can be made at some distance from the walls or boards.
Before lowering the conditioner, make sure that the blade is “out-of the ice”
or elevated so that it will not cut immediately upon lowering the conditioner
to the ice surface. See the “Blade Control” information in Chapter 9.
Note: To avoid catching the towel underneath the conditioner, lower the
conditioner only while driving slowly forward.
While on the ice surface and driving slowly forward, lower the conditioner
and start the conveyors immediately.
To lower the conditioner:
Push down on the conditioner valve handle completely. Allow time for the cylinder to travel
to the end of its allowable movement. You will normally hear a hissing sound produced
by the hydraulic uid passing over the relief valve when the conditioner has traveled fully
down or up. When you hear this return the valve to neutral. This will insure proper down
pressure has been applied. You should also feel the machine lift transferring weight to the
conditioner.
To start the conveyors (augers):
Pull up on the conveyor handle. The operator should be able to hear the conveyors rotating.
The operator should be able to observe the stream of snow through the viewing window as
the snow tank lls with snow. The conveyors should be stopped before the snow tank is
completely full to avoid plugging the vertical conveyor.
DANGER!
Turn off and remove the ignition key before adjusting,
repairing, cleaning, or servicing the conveyors.
If any part of the conveyor system becomes plugged or
clogged, or appears plugged or clogged, the conveyor
must be ushed out with water. Do not wear gloves or
jewelry when performing these functions.
Flushing the augers out with water must be done only
after the machine has been removed from the ice, the
auger control valve has been returned to its neutral
(off) position, and the ignition has been shut off.
Under no circumstances should the operator attempt
to clean or clear the conveyor system or parts around
it while the machine is on the ice or the power is on.
To do so, exposes the operator and others to serious
potential injury or death!
