WARNING"
To ensure safe operation of
your unit, all nuts and bolts must be checked
periodically for correct tightness.
To Sharpen Blade:
•
The blade can be sharpened with a file or on a
grinding wheel. Do not attempt to sharpen the
blade while it is still on the mower.
•
Follow the original angle of grind as a guide. Make
sure that each cutting edge receives an equal
amount of grinding to prevent an unbalanced blade.
An unbalanced blade will cause excessive vibration
when rotating at high speeds, may cause damage to
the mower and/or personal injury. Test the blade by
balancing it on a round shaft screwdriver or a blade
balancer.
•
If the blade is not balanced, remove metal from the
heavy side until it balances evenly.

ARNING:
As always, use a thick piece of
rag to handle the blade while sliding the belt
around it. Make sure the engine does not start
at all while doing this job.

engine pulley while pulling from the other side and
sliding it around the transmission pulley.

Put the mower down with all four wheels firmly
placed on one level.
