9.19 TO BACKLAP THE REELS __________________________________________________
Check the reel and the bedknife to determine if backlapping or
grinding will restore the cutting edge.
If wear or damage is beyond the point where the cutting edges can
be corrected by the lapping process, they must be reground.
To backlap:
1. Lower the reels to the ground, set the PTO switch in the OFF
position, set the parking brake in the ON position and stop the
engine.
2. Loosen the valve locknut at the valve stem on the front and
rear reel valves.
3. Start the engine and set the throttle to the slow position.
4. Enter Maintenance mode (
See Section 9.2
). Press the joystick
forward or backward until the
BACKLAP ENABLE?
screen is
shown on the LDU. Press the LDU button.
5. If the seven gang option is installed, press both buttons on the
top of the joystick.
6. If any of the reels are lifted, the
LOWER ALL ACTUATORS
screen is shown on the LDU. You must exit maintenance mode
and lower all the reels to the ground. Enter maintenance mode
and restart the backlap request.
7. The
10 MINUTES < START >
screen is shown on the LDU.
Use the joystick to adjust the timer. Press the LDU button.
8. The
ACTUATE PTO SWITCH
screen is shown on the LDU.
Move the PTO switch to the ON position. The reels will start to
rotate in the reverse direction.
9. The
XX MINUTES < QUIT >
screen is shown on the LDU.
When the LDU button is pressed, or the backlap timer is at 0
minutes, the reels will stop.
10. Both of the reel valves contain an adjustable valve(s) to control
the speed of the reels. Turn the valve to the left to decrease
the reel speed. Repeat for both valves.
11. After the desired speed is set, tighten the locknut to set the
adjustment.
12. Apply lapping compound, with a long handle brush, along the full length of the reel.
13. When the reels are honed, carefully and completely wash off the remaining mixture.
14. Repeat the full procedure on the other reels.
15. Repeat the backlap procedure if additional time is needed.
WARNING
To prevent injury, keep hands, feet and clothing away from rotating reels.
Never operate the engine without enough ventilation or in an enclosed area. The carbon monoxide in the exhaust
fumes can increase to dangerous levels.
