Bolens 120-280R000 - Manual (Page 11)

The best mowing pattern is one that allows the clippings
to discharge towards the uncut part of the lawn. This
permits recutting of the clippings to further pulverize
them. When cutting high weeds, discharge towards cut
portion, then recut at right angles to first direction.
For best results, cut off one-third or less of the total
length of the grass. Lawn should be cut in the fall as
long as there is growth.
This mower is designed to be operated at full throttle
to give you the best cut and do the most effective job
of bagging the cut grass.

WARNING: If you strike a foreign object,
stop the engine. Remove wire from spark
plug, thoroughly inspect the mower for any
damage, and repair the damage before
restarting and operating the mower. Exten­
sive vibration of the mower during opera­
tion is an indication of damage. The unit
should
be promptly inspected and
repaired.
ADJUSTMENTS
WARNING: Do not at any time make any
adjustment
to lawn mower without first
stopping engine and disconnecting spark
plug wire.
CUTTING HEIGHT ADJUSTMENT
An adjusting plate and thumb lever at each wheel posi­
tion provides cutting height adjustment. Each adjusting
plate has nine height positions. Height of cut will be
changed when the thumb lever is moved from one hole
to another. Simply depress the lever towards wheel and
move wheel and lever assembly to desired position. All
wheels must be placed in the same relative position.
See figure 12.
For rough or uneven lawns, move the wheels to a posi­
tion which will give a higher cutting height.
DRIVE CLUTCH ADJUSTMENT
The drive pinions should be a minimum of 1/8" from
the drive wheels when the clutch is disengaged (clutch
control handle is not squeezed against upper handle).
Refer to figure 6. When the clutch control is engaged,
the drive pinions should mesh with the tires.
If adjustment is necessary, loosen the screw which
secures the cable bracket on the handle. Adjust until
there is at least 1/8" of clearance. If additional adjust­
ment is required, unhook the cable from the clutch
handle, and move it to the higher hole to obtain less
clearance. Using the lower hole gives more clearance.
Retighten the cable bracket when the correct adjust­
ment is reached.
THROTTLE CONTROL ADJUSTMENT
If the throttle control needs adjustment or has been
replaced, adjust the throttle control as follows.
1. Loosen (do not remove) the screw on the cable
clamp so that the cable will move freely under the
clamp. See figure 13.
2. Place the throttle control lever on the handle all the
way forward to START position.
3. Place the control lever on the engine in the full
open position by pushing it as far toward the out­
side of the engine as it will go. Tighten the screw
on the cable clamp to secure the cable in this
position.
