Note: Backlapping speed may be increased by
moving the reel speed selector knob toward
"13." Each position will increase speed
approximately 100 rpm. After changing
selector, wait 30 seconds for the system to
stabilize at the new speed.
4.
Make initial reel to bedknife adjustments
appropriate for backlapping on all cutting units
that are to be backlapped.
5.
Start the engine and run it at idle speed.
DANGER
POTENTIAL HAZARD
Changing engine speed while backlapping
may cause reels to stall.
WHAT CAN HAPPEN
Reels may restart. Contact with rotating reels
will cause serious injury.
HOW TO AVOID THE HAZARD
•
Never place hands or feet in reel area
while engine is running.
•
Never change engine speed while
backlapping.
•
Only backlap at idle engine speed.
•
Never attempt to turn reels by hand or
foot while engine is running.
6.
Select either front, rear, or both backlap knobs
to determine which reels will be backlapped.
7
Move the Enable/Disable switch to the Enable
position. Move the Lower Mow/Lift control
forward to start backlapping operation on
designated reels.
8.
Apply lapping compound with a long-handle
brush (Toro Part No. 29-9100). Never use a
short-handled brush (Fig. 57).
Maintenance
1. Long handle brush
9.
If reels stall or become erratic while
backlapping, stop backlapping by moving the
Lower Mow/Lift control lever rearward. Once
the reels have stopped, move the desired reel
speed selector knob(s) one position closer to
"13." Resume backlapping by moving the
Lower Mow/Lift control lever forward.
10. To make an adjustment to the cutting units
while backlapping, turn reels OFF by moving
the Lower Mow/Raise lever rearward; move
the Enable/Disable switch to Disable and turn
the engine OFF. After adjustments have been
completed, repeat steps 5–9.
11. Backlap until the reels can cut paper.
12. When the cutting unit is adequately sharpened,
a burr will form on the front edge of the knife.
Using a file, carefully remove the burr without
dulling the cutting edge (Fig. 58).
