Operation
CAUTION
When the broom is engaged, it may drive the
unit in the reverse direction. If the broom height
is adjusted too low, the machine may move more
forcefully in the reverse direction, causing injury
and/or property damage.
Carefully check the broom height and adjust it
properly or contact your authorized EXMARK
SERVICE DEALER.
1. Set the engine throttle to the "FAST" position.
2. Place the speed selector lever into the desired
position and slowly squeeze the LH traction drive
lever.
Important: Make sure the traction drive
is engaged before operating the broom;
otherwise the broom may drive the unit in the
reverse direction.
3. To engage the broom, slowly squeeze the right
hand (broom) lever to the handle (Figure 9).
Figure 9
• If the engine slows down under a load or the
wheels slip, shift the machine into a lower gear.
• If the front of the machine rides up, shift
the machine into a lower gear. If the front
continues to ride up, lift up on the handles.
4. To stop the broom, release the right hand lever.
Checking the Sweeping Path
A broom sweeps with the tips of its bristles. When
too much down pressure is applied, the broom is no
longer using its tips; the broom is now working with
the sides of the bristles (like a mop). This limits the
flicking action of the bristles, sweeping effectiveness,
and can decrease broom life.
1. Drive to a flat dusty area and stop the machine.
2. With the engine running, with the throttle set
midway between "SLOW" and "FAST". Engage
the broom and allow the broom to sweep for
approximately 30 seconds.
3. Disengage the broom and stop the engine.
4. Wait for all moving parts to stop before leaving
the operating position.
5. Turn the engine on/off switch to the "OFF"
position.
6. Make sure the area swept equals the length of the
broom and 2-4 inches (51-102 mm) maximum
width.
1. 2–4 inches (51-102 mm)
maximum width
2. Length of broom
7. Adjust the broom height if necessary.
Adjusting the Broom Height
1. Drive to a flat dusty area and stop the machine.
2. Disengage the broom and stop the engine.
3. Wait for all moving parts to stop before leaving
the operating position.
4. Turn the engine on/off switch to the "OFF"
position.
5. To adjust the broom height, remove and retain the
pin from the adjuster sleeve and caster wheel tube.
