Stopping the Engine —————
ATTENTION: Before stopping an engine that has been operating at working load, idle the engine for at
least two minutes at 1,000-1,200 R.P.M. to cool hot engine parts.
1. Move throttle lever to idle position.
2. Turn ignition switch counter-clockwise to “off” position.
Propulsion —————
Never jerk the speed control lever quickly from one direction to the other, as this creates
severe loads and may shorten the life of hydraulic components.
Complete speed control of the machine is accomplished through the use of the Speed Control Lever. The
further forward from neutral, the faster the forward speed, and the further back from neutral the faster the reverse
speed. (It is not necessary to run the engine at full RPM if satisfactory blowing results can be obtained at a lower
engine speed. Lower engine RPM will result in less dust being generated by the blowing process.)
When ground speed is reduced due to increased loads, the Speed Control Lever should be moved toward
the neutral position. For example, when encountering a hill it may be necessary to move the speed control lever
toward neutral rather than full speed. This is the same as down shifting with a typical mechanical transmission.
This sweeper is capable of road speeds of approx 14 MPH. To obtain this speed, select “ROAD” on the
electrical switch for speed range and then move the Speed Control Lever forward. The electric switch to select
the speed range: “ROAD” or “FIELD” can be used at any time. However, the change in vehicle speed will
be more violent and abrupt at high engine RPM and high speed. It is good to throttle the engine down a bit to
make the speed shift change, and then throttle back up.
IMPORTANT: Sweeping in “ROAD” range may cause over-heating of the hydraulic oil and
can lead to serious damage of hydraulic components! USE “ROAD” RANGE ONLY FOR
TRANSPORT ON HARD DIRT OR PAVED ROADS.
Braking —————
To slow the sweeper, move the speed control lever towards neutral (or beyond) for desired deceleration by
means of dynamic braking.
The parking brake is located on the control console. Move the switch to the “on” position to engage the
brakes.
NOTE: The parking brake is a “wet brake” and requires the addition of approx 5.5 fl oz of oil. See
Specifications and Fluids page at the back of this manual for proper oil recommendation.
The parking brake is not intended to be used as a method of slowing the sweeper during
normal operation.
The brake is intended for parking purposes only. Make sure the brake is released before
attempting to drive the machine.
