SERVICE PROCEDURE
NOTE:
When tipping the mower to work on the
underside, always tilt the mower onto the LEFT wheels,
(after disconnecting the spark plug wire), to prevent
flooding the engine with gasoline and/or oil, which would
cause hard starting after servicing.
By returning your mower to an Authorized SNAPPER
Dealer on a yearly basis for inspection and addition
of any new devices to upgrade your mower, the
reliability of the unit's functions will be assured.
Your SNAPPER mower requires very little service,
however, it is important that the engine be serviced
at the intervals specified in the engine manual fur¬
nished with your mower.
To retain the integrity of your mower, only use Ge¬
nuine SNAPPER Replacement Parts.
Check the yellow pages under LAWN MOWERS for
the nearest SNAPPER Dealer. Always mention the
model and serial number of your mower when con¬
tacting the dealer for information, parts, or service.
For engine parts/service, check the yellow pages
under the heading ENGINES - gasoline, for the
nearest engine manufacturer's dealer.
LUBRICATION SCHEDULE
• ENGINE:
Change oil every 25 hours as specified in
engine manual; check oil level before each use.
'TRANSMISSION (on the self-propelled models ):
The transmission is filled with 4 ounces of SNAPPER
"00" grease at the factory and under normal usage, will
not require additional grease. It is recommended that
plug (A) be removed after every 25 hours of operation,
and a visual determination of the lubrication condition of
the transmission be made. If grease IS NOT visible on
the INPUT GEAR (the small gear below the plug
opening), add a small amount of SNAPPER "00" grease.
Reinstall the plug (A) after servicing the transmission.
Refer to FIG. 7.
SNAPPER "OO" grease is available in a convenient
squeeze container (Part No. 6-1017) at your SNAPPER
DO NOT spill oil on the surface of drive disc,
(on self-propelled models)
CUTTING BLADE SERVICE

Refer to FIG. 8 for blade condition. Replace the
blade if it is badly chipped, bent noticeably out of
balance, or has a notch worn in either tip - as shown
in example B.
The B wear pattern occurs more rapidly under sandy
soil conditions and appears between the flat surface
and upturned "lift" lip at each end of blade tip.
WARNING:
Never operate the mower with a blade
worn to the extent shown in example C - the "tip"
could fly off and cause personal injury or property
damage.

Re-install the blade with the components in proper
sequence as shown in FIG. 9.
When the blade's cutting edges have become dull
(while in otherwise good condition), sharpen on a
grinding wheel at an angle of 22 to 28 degrees.
The cutting surface (on each end) should extend in¬
ward about 3-1/2" from the tip. After sharpening,
check the blade for balance - a blade "out of
balance" will cause excessive vibration. Rebalance „
5-
as required.
Inspect blade at frequent intervals for tightness and
condition.
DO NOT
substitute any components! Make sure the
flange on each side of blade (at the mounting hole)
fits over the edge of the blade drive hub (A). Tighten
