3.11 BLADE SHARPENING
__________________________________________________________________
1.
When dressing or resharpening the blade DO NOT
follow the original angle of grind as shown in “AA”.
Grind new cutting edges on a diagonal as shown in
“AB”.
Figure 3C
2.
As a consequence of all resharpenings, a total loss
off of 1/2 in. (13 mm) of metal is allowable.
3.
Make sure each cutting edge is equally sharpened
to prevent an unbalanced blade. This will cause
excessive vibration and may damage the mower.
4.
Use a blade balancer to check the blade.
Beware of cutting edges.
Always wear gloves for safety
during blade maintenance activities.
3.12 SAFETY INTERLOCK SYSTEM _______________________________________________
Do not by-pass the safety
interlock system or switches.
They are included for your protection. Check the
safety system and mechanisms daily for proper
operation. If a defect is found, repair immediately.
Do not operate the equipment in a defective
condition.
The safety interlock system is designed to allow the
operator to start the mower only if the blades are
disengaged, the parking brake is set, and the steering
control levers are in the outward neutral lock position.
1.
The engine will shut off if the operator is not in the
seat and;
a.
the parking brake is disengaged.
b.
the control lever is moved out of the neutral lock
position.
2.
Check the switch activating mechanism and connec-
tions on a regular basis to ensure;
a.
the electrical wiring is not cracked or broken.
b.
all connections are tight.
c.
engine components (fuel, Ignition system) are
functioning properly.
3.
Check the Neutral Control switches to ensure the
plungers are fully depressed when the Neutral
Control Levers are in the lock position.
4.
Check the Park Brake switch to ensure the plunger
is fully depressed when in the drive mode.
