ELECTRIC MOTORS
The carbon brushes on the propelling and
accessories motors should be inspected after
every 800 hours of machine operation.
BELTS AND CHAINS
VACUUM FAN BELT
Check the vacuum fan belt tension and wear after
every 200 hours of operation. The correct tension
is when the belt deflects 12.7 mm (0.50 in) from a
force of 15 kg (30 to 40 lb) at belt midpoint.
MAIN BRUSH BELT
Check the main brush belt for wear after every
200 hours of operation. The idler keeps tension on
the belt. The tension is set manually.
PROPELLING CHAIN (For machines below
serial number 002363)
The front wheel chain drive/support propels the
front wheel to drive the machine. Check the
propelling system and chain tension every
100 hours. Proper chain tension is 3 mm (.125 in)
from slight tension applied at the midpoint of the
longest span. Lubricate the propelling chain with
SAE 30--weight engine oil after every 100 hours of
operation.
