to a complete stop, disconnect spark plug wire and move wire away from spark plug. Remove ignition
key, if so equipped,
Failure to follow these instructionscan result in serious personalinjury or propertydamage.
Adding Gear Of/to the
PTOPower Unit Transmission
1. Do steps 1 and 2 of Checking the
Power Unit OL/Leve/ on page 32=
2. Using a 3/4" wrench (or socket),
remove the boIt securing the handlebar
base to the top of the transmission (prop
the handlebars first to prevent them from
falling).
Then, unpiug tire Forward Interlock wire
harness receptacleat the bottom of the
handlebars. Set the handlebar baseand
boit aside on a clean surface. The bolt
hoie in the top of the transmission is the
gear oiI filI hole
(A,
Figure 5=9)=
3. Slowly pour gear oiI through a clean
funnel into the transmission. Stop when
gear oil begins to flow from the oii ievet
check hote on the ieft side of the transo
mission (B, Figure 5=7)=
4. Reinstali the oii ievel check plug.
Tighten it securely.
5. Reinstali the handlebars using the
mounting boit previously removed. Align
the handlebars so they point straigirt
backwards, not at an angte= Thentighten
the mounting bolt securely.
6. Reconnect the Forward Interlock wire
harness to the receptacle. Be certain it's
secure=
7, Test operation of the Forward Interlock
Safety System. See Section 4 for a
procedure.
Draining and Filling the
PTOPower Unit Transmission
1. Piace a shaiiow pair under the trans-
mission gear oil drain plug (B, Figure
5=9).
2. Removethe oii levelcheck plug (Figure
5-7) with a 3/8" wrench. This vents the
transmission for faster oil draining.
Figure 5=9: Gear off fill hole (A) and
gear off drain location (B).
3. Using the 3/8" wrench, remove the
drain plug (B, Figure5-9). The gear oil
wiii drain quite slowly since it is thick.
After about two quarts have drained, tiit
the tiiier forward so any oii at tire rear of
the transmission will drain out=
4, Cleanthe drain plug threads, put non=
hardening gasket sealant on the threads,
and reinstall piug=
5. Refiii the transmission with the correct
amount of gear oii before operating the
tiiier again=When oii seeps from the oii
leveicheck hoie, the right amount of gear
oil has been added= ReplacealI plugs=
Adding 8ear Oil to the Tine
Attachment Transmission
1. Select the right Depth Reguiator Lever
setting:
a. If fiiiing an empty transmission, raise
the Depth Regulator Leverso tines
are on the ground=
b. If topping off the gear oii, move Depth
Regulator Leverdown to engage its
top notch.
2. Remove dipstick from tine attachment
(Figure5=8),
3. Slowly add gear oiI in the dipstick hole.
Add 1/2=ounceat a time to avoid overfill-
ing. It takes about 12=1/2 ounces.
4. Take dipstick readings frequently. Stop
when oii reactres"Coid" range marking on
dipstick. Replacedipstick securely.
Braining and Fifling the Tine
Attachment Transmission
1, The tine attachment transmission is
not equipped with an oii drain plug. To
drain just a small amount of gear oiI,
remove the dipstick and tiit the attach-
ment forward (first uncoupling it from the
Power Unit).
2. Forcompiete drainage, remove the ieft-
side tine assembly (refer to Bolo Tine
Naintenance for instructions), then
remove just one of the iower screws from
the tiiier housing cover (Figure5-10). To
speeddrainage, remove the tine attach-
ment dipstick to vent transmission.
Figure 5-10: Remove housing cover
screw to drain tine attachment
transmission gear oil
NOTE: if you find a plastic washer on the
cover screw you remove, discard the
washer. There is no need to install a
repiacementwasher.
3. Once ali gear oii has drained, reinstali
the housing cover screw secureiy (first
coat its threads with non-hardening
gasketsealant).
4. Be certain to refiii the transmission
with the correct amount of gear oil before
operating the tiller again.
