Sand Application Rate
The rate of sand applied depends on the gate setting
and the gear/range setting. Sand varies in moisture
and coarseness (size of grain) which affects the rate.
Take these factors into consideration when deciding
the amount of sand required for the application. Test a
small area to decide the correct amount. To increase
the application rate, either open the gate to a higher
scale mark or shift the Workman vehicle to a lower
gear.
Note:
On vehicles with serial numbers 240000001
and up, the sand application rate will decrease when
you turn the vehicle. Avoid making sharp turns when
topdressing.
To ensure consistent application, from green to green,
it is highly recommended to use a tachometer and/or
hand throttle to maintain constant engine speed while
topdressing.
WARNING
Tipping or rolling the vehicle on a hill will
cause serious injury.
If the engine stalls or you lose headway on a
hill, never attempt to turn the vehicle around.
Always back straight down a hill in reverse
gear.
Do not back down in neutral or with the clutch
pressed, using only the brakes.
Never add sideboards or panels to the top of
the hopper to increase the load capacity. The
additional weight will cause tipping or rolling
of the vehicle and lead to serious injury.
Do not drive across a hill: drive up and
down the hill. Avoid turning on a hill. Do
not accelerate or decelerate fast. A sudden
change in speed can initiate a tipover.

Sand Precautions
The TopDresser 1800 is equipped with a flexible gate
edge
(Figure
20) and spring release mechanism to
reduce the chance of sand chunks or rocks getting
lodged during operation. To ensure long belt life, sift
or check the sand for rocks with sharp edges that may
damage the conveyor belt.

Operating the Machine in
Cold Weather
You can use the machine in cold weather, with
certain limitations, to apply a salt/sand mixture on
pavement for ice control. The PVC conveyor belt
material becomes very stiff in cold weather and
requires more power to operate. The life of the belt is
reduced by approximately 50% when operated below
temperatures of 5 degrees C (40 degrees F). Under
no conditions should the topdresser be operated
below temperatures of -7 degrees C (20 degrees
F).
1.
Increase the belt tension by adjusting the spring
compression to 101 mm (4 inches). Refer to
Adjusting the Conveyor Belt (page
2.
Always run the belt before adding material, to
ensure that no moisture has frozen the belt
system. Damage to the belt or roller may occur
if slippage occurs between the belt and the drive
roller.
Important:
Set the belt tension to the normal
112 mm (4-7/16 inches) spring compression
adjustment before operating the machine
under normal temperature conditions.
