DRIVE WHEEL CHAIN (Refer to the Front Wheel
Group in the Parts section)
The drive wheel chain transfers power from the
differential shaft to the drive wheels. Check the
chain condition and tension every 200 hours of
operation.
REPLACING AND ADJUSTING THE DRIVE
WHEEL CHAINS
1. Turn off machine and set parking brake.
FOR SAFETY: Before leaving or servicing machine,
stop on level surface, apply parking brake, turn off
machine and remove key.
2. Raise rear cover.
3. Disconnect batteries from machine.
4. Chock the rear wheels. Jack up and remove the
front tire.
5. Remove the chain guard and tensioner disk.
6. Check the drive wheel chain for excessive wear.
Replace if necessary.
7. Check the drive wheel and differential shaft
sprockets to proper alignment. If they are not
lined up, loosen the setscrews on the
differential shaft sprocket, align the sprockets,
and tighten the setscrews.
8. Replace the chain guard and tensioner disk.
9. Check the chain tension. There should be 1/2
inch (1 5 mm) slack measured midway between
the sprockets. To adjust the tension, loosen the
chain guard mounting bolt and rotate the disk.
Tighten the chain guard mounting bolt.
10. Replace the tire and slowly lower the machine
to the floor.
11. Repeat the procedure for the other drive tire.
SKIRTS AND SEALS (Refer to the Frame Group
and the Main Broom Group in the Parts section)
The main broom skirts prevent dust from exiting the
main broom chamber. The skirts should be
inspected for wear or damage daily. When correctly
adjusted, they should clear the floor by 0 to 1/8 inch
(0 to 3mm).
NOTE: Original equipment skirts are provided with
“Perform Alert™” wear indicators. The wear
indicator is raised horizontal line near the lower edge
of the skirts. When a skirt is worn to this line it
should be replaced. A skirt can be adjusted many
times before it wears to the “Perform Alert™” strip.
During daily inspections the “Perform Alert™”
indicators are useful in determining when skirts are
close to requiring replacement.
