Backlapping

DANGER
DURING BACKLAP OPERATION REELS ARE
UNDER POWER. CONTACT WITH ROTATING
REELS CAN RESULT IN PERSONAL INJURY.
DO NOT ADJUST CUTTING UNITS WHILE EN-
GINE AND REELS ARE OPERATING. IN-
STRUCT OPERATOR TO STOP THE REELS
AND SHUT THE ENGINE OFF WHEN ADJUST-
MENT IS NECESSARY.
Use a good grade of medium grit (80 courseness)
lapping compound with a water soluble carrier so the
compound will be easily washed away after completion
of the operation. Dry lapping compound should be
mixed with liquid detergent until it has a free-flowing
consistency.
Two people are required to perform backlapping. Good
communication between one another is necessary and
caution should be used when making each move. With
one person on the seat to operate the controls (opera ­
tor) the other performs the backlapping operation.
NOTE: Before starting the engine raise the grass deflec­
tor on the #1 cutting unit (center) and tighten fasteners
to retain the deflector in the raised position.
1st persons duties (Operator):
A. Sit on the seat and engage parking brake.
B. Start the engine and run at minimum throttle.
Lower either:
1.) the center cutting unit (#1) or
2.) the left hand (#2) cutting unit or
3.) the right hand (#3) cutting unit.
With the #2 & # 3 cutting units up and latched
(automatically shut off) and the #1 cutting unit down,
backlap the center (#1) cutting unit from the rear of

UNDER NO CIRCUMSTANCES USE A SHORT-
HANDLED PAINT BRUSH TO APPLY BACK-
LAPPING COMPOUND. A ROTATING REEL

PAINT BRUSH AND THE USERS HAND INTO
THE REEL CAUSING SERIOUS PERSONAL
INJURY.
B. Dip 3 in. (76 mm) paint brush attached to Toro
Part No. 29-9200 Handle Assembly into lapping
compound. Stand clear and instruct operator to en­
gage reel into backlap mode.

of the reel, assuring that all reel blades are covered.
Whenever noise of reel against the bedknife begins
to disappear or, an uneven concentration of material
appears on the reel, redistribute the compound with
the brush.
