Bolens 3BA サービスマニュアル

 

IMPORTANT: 

Check the adjustments 

as instructed and make 

any final adjustments 

necessary before 

operating the unit. 

Check all nuts and  

bolts for tightness. 

Failure to follow these 

instructions may cause 

damage to unit. 

It is not recommended 

that you operate this 

snow thrower on gravel 

as loose gravel can be 

easily picked up and 

thrown by the auger 

causing personal injury 

or damage to the snow 

thrower. However, if 

you have to operate 

it on gravel, keep the 

skid shoe in the highest 

position for maximum 

clearance. 

The space between the shave plate and the ground can 
be adjusted. Refer to Figure 7 for location of shave plate 
and skid shoes.
For close snow removal, place skid shoes in the low 
position. When the area to be cleared is uneven, place 
skid shoes in the middle or high position. See Figure 4.
NOTE: It is not recommended that you operate this 
snow thrower on gravel as loose gravel can be easily 
picked up and thrown by the auger causing personal 
injury or damage to the snow thrower. However, if you 
have to operate it on gravel, keep the skid shoe in the 
highest position for maximum clearance. 
1.  Adjust skid shoes by loosening two hex nuts and 

carriage bolts on each skid shoe, and move the skid 
shoe to the desired position. See Figure 4.

2.  Make certain the entire bottom surface of skid shoe 

is against the ground to avoid uneven wear on the 
skid shoes. 

3.  Tighten nuts and bolts securely.

1.  Make sure that the drive cable is routed parallel to 

the left upper handle, then across the top of the 
lower handle and finally parallel to the right lower 
handle.  See Figure 5.

2.  Three cable ties have been used to loosely tie the 

two control cables to the lower handle. Two of these 
cable ties are on each arm, and third on the top 
cross bar of the lower handle. Tighten these cable 
ties to secure the cable to the lower handle. See 
Figure 5.

Periodic adjustment to the auger control cable may be 
required due to normal stretch and wear on the belt. 
Adjustment is needed if the augers seem to hesitate 
while turning, but the engine maintains speed, or 
continue turning with the auger control disengaged.

1.  Loosen the rear hex bolt on the cable adjustment 

bracket.  See Figure 6.

2.  Slide the cable adjustment bracket backwards 

taking out the slack in the auger cable. 

3.  Retighten the rear hex bolt
4.  Start engine and verify auger control engages and 

disengages properly.

NOTE: If auger continues to rotate with the control 
disengaged, shut off engine and readjust.
