Craftsman 917.273663 - Manual (Page 14)

3. Allow one minute for transmission to
warm up. This can be done during the
engine warm up period.
• The attachments can be used during
the engine warm-up period after the
transmission has been warmed up and
may require the choke control be pulled
out slightly.
NOTE: if at a high altitude (above 3000 feet)
or in cold temperatures (below 32 F) the
carburetor fuel mixture may need to be ad­
justed for best engine performance (see “TO
ADJUST CARBURETOR” in the Service and
Adjustments section of this manual).
PURGE TRANSMISSION
^CAUTION: Never engage or disengage
freewheel lever while the engine is running.
To ensure proper operation and per­
formance, it is recommended that the
transmission be purged before operating
tractor for the first time. This procedure will
remove any trapped air inside the trans­
mission which may have developed during
shipping of your tractor.
IMPORTANT: Should your transmission
require removal for service or replace­
ment, it should be purged after reinstall­
ation before operating the tractor.
1. Place tractor safely on level surface
with engine off and parking brake set.
2. Disengage transmission by placing
freewheel control in disengaged posi­
tion (See “TO TRANSPORT” in this
section of manual).
3. Sitting in the tractor seat, start engine.
After the engine is running, move throt­
tle control to slow position. With motion
control lever in neutral (N) position,
slowly disengage clutch/brake pedal.
4. Move motion control lever to full
forward position and hold for five (5)
seconds. Move lever to full reverse
position and hold for five (5) seconds.
Repeat this procedure three (3) times.
NOTE: During this step there will be no
movement of drive wheels. The air is being
removed from hydraulic drive system.
5. Move motion control lever to neutral
(N) position. Shutoff engine and set
parking brake.
6. Engage transmission by placing free­
wheel control in engaged position (See
“TO TRANSPORT” in this section of
manual).
7. Sitting in the tractor seat, start engine.
After the engine is running, move
throttle control to half (1/2) speed.
With motion control lever in neutral (N)
position, slowiy disengage clutch/brake
pedal.
8. Slowly move motion control lever for­
ward, after the tractor moves approxi­
mately five (5) feet, slowly move motion
control lever to reverse position. After
the tractor moves approximately five
(5) feet return the motion control lever
to the neutral (N) position. Repeat this
procedure with the motion control lever
three (3) times.
Your transmission is now purged and now
ready for normal operation.
MOWING TIPS
• Mower should be properly leveled for
best mowing performance. See “TO
LEVEL MOWER HOUSING” in the
Service and Adjustments section of this
manual.
• The left hand side of mower should be
used for trimming.
• Drive so that clippings are discharged
onto the area that has already been
cut. Have the cut area to the right of
the tractor. This will result in a more
even distribution of clippings and more
uniform cutting.
• When mowing large areas, start by
turning to the right so that clippings will
discharge away from shrubs, fences,
driveways, etc. After one or two rounds,
mow in the opposite direction making
left hand turns until finished.
14
If grass is extremely tall, it should be
mowed twice to reduce load and pos­
sible fire hazard from dried clippings.
Make first cut relatively high; the second
to the desired height.
Do not mow grass when it is wet.
Wet grass will plug mower and leave
undesirable clumps. Allow grass to dry
before mowing.
Always operate engine at full throttle
when mowing to assure better mowing
performance and proper discharge of
material. Regulate ground speed by
selecting a low enough gear to give the
mower cutting performance as well as
the quality of cut desired.
When operating attachments, select a
ground speed that will suit the terrain
and give best performance of the at­
tachment being used.
