STEP 3: Add Motor Oil
A. The unit’s engine was shipped
without motor oil which MUST BE
ADDED before the engine is started.
B. See the Engine Owner’s Manual you
received for filling instructions and for
the correct oil specifications for your
engine. Engine must be level when
checking oil level. In ambient tempera-
tures above 40
0 F, use a high-quality
SAE 30 weight detergent oil classified
for Service SF, SG or SH. Use no spe-
cial additives. Do not mix oil with fuel.
C. Lift or slide plastic debris shield (P,
Figure 2-3) up and tilt it forward to ac-
cess engine dipstick/oil fill hole (R).
D. Add oil according to the instruc-
tions in the Engine Owner’s Manual.
E. Lift and tilt the plastic debris shield
back and push it down to secure it.
STEP 4: Connect Battery
Wires and Charge Battery
(electric start model only)
A. Connect wire lead (T, Fig. 2-4) from
the battery (S) to the connector (U) on
the main wire harness. Align connec-
tors so wire colors are in line. Press
both plastic connectors together
securely.
B. To charge the battery, the battery
charger shipped to you must first be
connected to the wire harness at loca-
tion “V” (Fig. 2- 5). Then plug the
charger box (W, Fig. 2-5) into a
grounded 120V wall outlet.
C. Initially charge battery for 24 hours
before using electric starter. After
charging, unplug the charger from the
wall outlet first, then disconnect the
wire harness (V, Fig. 2-5). (Prior to
and after removing machine from win-
ter storage, also charge battery for 24
hours.)
STEP 5: Check Trimmer
Head Hardware
Check the tightness of the hardware
securing the trimmer head at two loca-
tions (X, Figure 2-6) and the hardware
that secures the line clamps at two lo-
cations (Y). You may rotate the trim-
mer head by hand to make access to
the hardware easier. Tighten the hard-
ware securely.
NOTE: The small round hole on the top
of the deck near the front of the ma-
chine is a service entryway. Its use is
explained in “Section 5: Maintenance.”
IMPORTANT: The trimmer head hard-
ware is designed to be permanently
installed and is not removable. Do
not attempt to replace it with non-fac-
tory specified hardware.
