Backlapping
Danger
During the backlap operation the reels are under
power. Contact with rotating reels can result in
personal injury.
•
Do not adjust the cutting units while the engine
and reels are operating.
•
Instruct the operator to stop the reels and shut
the engine off when an adjustment 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 (operator) the
other performs the backlapping operation. Note: Before
starting the engine raise the grass deflector on the #1
cutting unit (center) and tighten fasteners to retain the
deflector in the raised position.
Operator Duties
1. Sit on the seat and engage parking brake.
2. Turn reel speed knob counterclockwise to slowest (#1)
position.
3. Start the engine and run at minimum throttle. Lower
either:
•
The center 3 cutting units (#1, 2 & 3 ) or
•
Left-hand (#4) cutting unit or
•
Right-hand (#5) cutting unit
The center 3 cutting units run and shut off together.
With the #4 & #5 cutting units up and latched
(automatically shut off) and the #1, #2 & #3 cutting
units down, backlap the center (#1) cutting unit from
the rear of the machine with the long handled brush.
Backlap the #2 and #3 cutting units from the front of
the machine.
4. Wait for second person’s instruction to engage reels in
backlap mode. Pull up on control lever and turn the
reel speed knob counterclockwise to the backlap
position.
5. Follow the second person’s instructions. Be prepared
to stop reels and engine quickly in case of an
emergency.
Duties for Second Person
1. Instruct operator when to start and stop reels.
Danger
Contact with the reel or other moving parts can
result in personal injury.
•
Stay away from the reel while backlapping.
•
Never use a short handled paint brush to apply
backlapping compound.
2. 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 engage
reel into backlap mode.
3. Apply lapping compound evenly over full length of the
reel, ensuring 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.
