• Save all instructions
WARNING
Disconnect the spark plug before performing maintenance.
Maintain the mower with care. Inspect the mower periodi-
cally. If the mower is not working properly or damaged,
have it repaired by a qualified service center. Do not
change engine governor setting or overspeed the engine.
Do not remove or modify any parts. Removing or modify-
ing parts could lead to injury, damage the mower and will
void the warranty. Use only genuine Powermate
ment parts and accessories. Use of any non-Powermate
parts or accessories could lead to injury, damage to the
unit, and void your warranty.
GENERAL MOWER CARE
1. After each use, remove any grass clippings or debris
from the top of the mower deck and engine area with a
brush or lawn and garden blower.
2. Periodically clean underside of the mower deck to pre
vent buildup of grass clippings, etc.
a) Before cleaning the underside of the deck, always
drain the fuel tank by running the engine till the tank
is empty. Disconnect the spark plug wire before
performing this or any other maintenance.
b) Tip the mower to expose the underside of the
mowing deck.
NOTICE
Always tip the mower so it is resting on the side of the deck
and the air filter side of the engine is facing up. Make sure the
lawn mower is resting in a stable position before beginning to
clean the deck. Never tip the mower more than 90 degrees in
any direction and do not leave the mower tipped for extended
periods of time. Oil can drain into the top part of the engine
and cause starting problems.
c) Scrape excess grass clippings with an appropriate
tool. Do not spray deck with water.
3. Using a light lubricating oil:
a) lubricate pivot points on the blade control lever at
least once each season.
b) lubricate the wheels at least once each season.

BLADE CARE

CAUTION
Use extra care when servicing mower blades. Blades are
sharp. To protect your hands, wrap the blade or wear gloves
when handling.
1. Periodically inspect the blade and blade adapter for
wear or damage, especially if you strike a foreign object.

2. Remove blade and adapter from the crankshaft.
3. 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. When sharpening the blade, follow
the original angle of grind. Grind each cutting edge
equally to keep the blade balanced. To check for blade
balance, place blade on a round shaft screwdriver.
Remove blade material from the heavy side until it
balances evenly.
CAUTION
An unbalanced blade will cause excessive vibration when
rotating at high speeds. It may cause damage to mower and
could break causing personal injury.

of the blade adapter with light oil. Slide the blade
adapter onto the engine crankshaft.
