TROUBLESHOOTING
WARNING: Before servicing unit, engine MUST be off.
PROBLEM ANSWER/COMMENT
Belt glazed or slipping 1. Limit maximum depth of cut to 2 1/2”.
2. If the Blade Lift Springs are worn they will allow the blade to
cut too deeply, which causes the belt to slip. Replace if
necessary.
3. Be sure the maximum RPM is not over 3000.
4. Be sure the correct BlueBird belt is being used. If not,
replace with a BlueBird belt.
5. Check to see if the Tension Cable is out of the pulley. Install
cable in pulley and squeeze bracket sides to minimize
the gap to pulley.
6. If the Gear Box Pulley or the Engine Pulley is wet, oily, or
damaged, clean or replace.
7. Belt tension can be increased by tightening the Cable
Tension nut.
Unit is creeping The transmission contains a centrifugal clutch and may creep
if left in gear. Some creeping is normal because of the lubricant
resistance between the clutch plates. Also, too heavy a
lubricate in Gear Reducer can cause creeping. Use 10W - 30 oil.
1. Put in neutral - unit will not creep.
2. RPM at idle should be 1,400 (+200/-150). Clutch will en-
gage at 1,800 RPMs. A high idle RPM may cause creeping.
3. If unit continues to creep, contact your local BlueBird dealer
or servicing dealer.
Bolts breaking 1. The vibration of the machine may cause bolts to come
loose. Check and tighten all bolts periodically.
Tires wearing too quickly 1. Tire wear is normal and to be expected. Running the
machine on excessively hard or abrasive surfaces can
increase wear.
