3.0
Owner's of the Black & Decker Lawn Mower LM175 gave it a score of 3.0 out of 5. Here's how the scores stacked up:
PREVENTING CORROSION
Fertilizers and other garden chemicals contain agents that greatly
accelerate the corrosion of metals. If you use the mower in areas
where fertilizers or chemicals have been used, the mower should be
cleaned immediately afterwards.
Wipe all exposed parts with a damp cloth. You may lubricate only metal
parts with a light petroleum based oil. Do not lubricate wheels.
MAINTENANCE
Before each mowing session unplug the mower and ensure that the
blade has stopped. Check all nuts, bolts and screws to ensure proper
tightness, Be sure to check the blade fastening system.
IMPORTANT: To assure product SAFETY and RELIABILITY, repairs,
maintenance and adjustment should be performed by authorized
service centers or other qualified service organizations. Use only
identical replacement parts.
Inspect and thoroughly clean your mower at the beginning of each
mowing season for longer life and better performance.
From time to time turn the mower off and wait for the blade to stop.
Then unplug the power cord and turn the mower on its side. Using an
object such as a stick or rag, wipe out any accumulation of grass in the
blade area. Also clean out any grass or debris which may be packed
around the discharge/mulch door area. Be careful of the sharp edges
of the blade.
REMOVING AND INSTALLING BLADE
(FIGURE 9, 10, 11)
1. RELEASE SWITCH LEVER TO TURN MOWER OFF, WAIT FOR
THE BLADE TO STOP, AND UNPLUG MOWER. THEN TURN
THE MOWER OVER FOR ACCESS TO THE BLADE.
2. Use a piece of 2x4 wood (about 2 feet long) to keep blade from
turning while removing flange nut.
3. Wear gloves and proper eye protection. Be careful of sharp edges
of blade. Position wood and remove flange nut as shown in
Figure 9.
4. Remove square metal blade spacer, square plastic blade insulator,
and blade (Figure 10). Examine blade insulator for damage and
replace if necessary.
5. When replacing sharpened or new blade on shoulder of fan, make
sure the “GRASS SIDE” on the blade will be facing the ground
when the mower is returned to its normal upright position. After
installing blade, place blade insulator on blade such that the raised
lips on one side engage the edges of the blade. Then install the
blade spacer so that it sits inside the raised lips on the other side of
the blade insulator. Be sure to align the flats in the hole of the
blade spacer with the flats of the shaft, rotating the blade and blade
insulator together as necessary. Position piece of wood to keep
blade from turning (Figure 11). Install flange nut with the flange
against the blade spacer and securely tighten.

SHARPENING AND BALANCING THE BLADE:
(FIGURE 12,13)
1. BE SURE THE SWITCH LEVER IS RELEASED AND THE BLADE
HAS STOPPED AND THE CORD UNPLUGGED BEFORE
REMOVING THE BLADE.
2. At all times be careful of sharp edges of blade.
3. Remove blade from mower. See instructions for removing and
installing blade.
4. Secure blade in a vise as shown in Figure 12.
5. Wear proper eye protection and be careful not to cut yourself.
6. Carefully file the cutting edges of the blade with a fine tooth file or
sharpening stone, maintaining the original cutting angle.
7. Check balance of blade by placing center hole in blade over a nail
or round shank screwdriver, clamped horizontally in a vise. If either
end of the blade rotates down, file off additional material from that
end. Blade is properly balanced when neither end drops.
