Check for Cause of Problem in Order Shown:
PROBLEM: MAIN MOTOR WILL NOT RUN.
1.
Check that the hoods safety switch, (Page 4, Item 17), is firmly down.
2.
Check battery voltage. (When voltage is too low, circuit breaker will cut out).
3.
Check for loose circuit wiring.
4.
Check for defective on/off switch.
5.
Check for defective relay.
6.
Check for defective circuit breaker.
7.
Check and replace motor brushes. Check also for burnt motor armature.
PROBLEM: SIDE BROOM MOTOR WILL NOT RUN; MAIN BROOM IS OK
Can you rotate the broom by hand? If no, then:
1.
Check In-Line fuse. (This is in the wiring harness
on early machines, and mounts under the
hood, on the left-hand under side lip of the
body. Current machines use a circuit breaker,
situated in the same location).
2.
Check too see that the wiring harness on the
side broom arm has not become disconnected.
3.
Check the side broom switch.
4.
Check broom motor.
If you can rotate the side broom by hand, then:
1.
Check that the drive connector, inside bearing
tube, has not become disconnected. It will do
this to save the motor and gear drive.
2.
Check the side broom motor.
PROBLEM: MAIN BROOM WORKS, BUT MAIN BROOM DOES NOT TURN.
1.
Check to see if something is caught in main broom, such as strapping. This material will wind
itself around the edges of the broom, locking it up and causing the belt to slip.
2.
Check both drive belts for wear and adjustment.
3.
Check the Main Broom Belt Tensioner. The belt tensioner moves constantly to take up slack in
the belt as the broom moves up and down with floor irregularity. It should be greased with
chassis grease every two years.
To grease: Unscrew vertical Allen-head retaining screw (Item B) BEFORE unscrewing
lateral Allen-head screw (Item A).
Remove lateral screw (A) and insert grease in arm's Oilite bearing. Reassemble. Do not
overtighten lateral screw (A) or arm will bind. Screw in (B) once position of (A) is correct.
PROBLEM: MOTOR RUNS, BUT MACHINE WILL NOT SELF-PROPEL.
1.
Make sure belt between motor and transmission is
adjusted properly.
2. See if clutch slips. If so, adjust, following the procedure in
this book. If adjustment cannot make clutch work properly.
3.
Replace the rubber clutch donut.
4.
Check chain and sprocket
on differential axle.
