Maintenance And Repair; Tips For Best Edging Results; Blade Replacement; Changing The Oil - Craftsman 316.773800 Operator's Manual

TiPS FOR BEST EDGING RESULTS
• After starting the engine, keep
the unit tilted back so the blade
does not touch the ground.
Move the unit to the desired
location and slowly lower the
blade into the ground.
Do not force the edger. Edge
the first time at a lesser depth
(no more than 1/2" depth cut
per pass), then do the area
again with a deeper setting.
• Walk the edger at a slow, even
pace.

Check the blade condition (Fig. 15). As it wears it becomes smaller, thus
reducing the cutting depth performance. Replace the blade when it no
longer makes contact with the ground.

BLADE REPLACEMENT
1. Place the 5/16" Allen wrench
in the spindle hole (Fig. 16).
2. While holding the Allen
wrench in place, loosen the
nut with a 15/16" wrench by
turning it counterclockwise
(Fig. 16).
3. Remove the nut and blade.
Keep the nut for new blade
installation.
4. Install the new blade and nut
(Fig. 17).
NOTE: Make sure the blade
edges are facing the
proper direction (Fig. 17).
The unit will not function
correctly if the edger
blade is installed
backward.

CHECKING THE OiL LEVEL
The importance of checking and maintaining the proper oil level in the
crankcase cannot be overemphasized. Check oil before each use:
1. Stop the engine and allow oil to drain into the crankcase.
2. Place unit on a flat, level
surface.
3. Keep dirt, grass clippings
and other debris out of the
engine. Clean the area
around the dipstick before
removing it.
4. Remove the oil fill plug.
5. Look into the oil fill hole, use
a flashlight if needed. The oil
should be just touching the
inner most thread (Fig. 18).

6. If the oil level is not touching

the inner most thread on the
oil fill hole, add a small
amount of oil to the oil fill hole
and recheck (Fig. 21). Repeat
this procedure until the oil
level reaches the inner most O-Ring
thread on the oil fill hole.
NOTE: Do not overfill the unit.

NOTE: Make sure the O-ring is Hole
in place on the oil fill
plug when checking and
changing the oil (Fig. 19). Fig. 19
CHANGING THE OiL
Change the oil per the Maintenance Schedule. Change the oil while the
engine is still warm. The oil will flow freely and carry away more impurities.
1. Remove the oil fill plug.
2. Pour the oil out of the oil fill hole and into a container by tipping the unit
to a vertical position (Fig. 20). Allow ample time for complete drainage.
3. Wipe up any oil residue on the unit and clean up any oil that may have
spilled. Dispose of the oil according to federal, state and local
regulations.
4. Refill the crankcase with
3.04 fl.oz. (90 ml) of SAE 30
SF, SG, SH oil.
NOTE: Use the bottle and
spout saved from initial
use to measure the
correct amount of oil.
The top of the label on
the bottle measures
approximately 3.04 fl.oz.
(90 ml) (Fig. 22). Check
the level, See Checking
the Oil Level. If the level
is low, add a small
amount of oil and
recheck. Do not overfill
(Fig. 18).
5. Replace the oil fill plug.
