Assembly
Safety Interlock System
Your machine is equipped with a Safety Interlock
System (see Figure 4) which prevents the engine from
starting unless the collection bag or blower deflector is
installed. The rod (A in Figure 4) must be positioned as
shown in the slot (B) in order to start the engine.
The system also stops the engine if the operator
attempts to remove the bag or deflector while the engine
is running. When the rod is not in place, a circuit closes
to ground out the engine.
If the safety interlock system fails, shut off the engine
and do not operate the machine until the system has
been repaired. Contact your local Sears Service Center
for repairs.
WARNING
To avoid personal injury or property damage, do not
operate this machine unless the safety interlock
system is functioning properly.
STEP 3: Add Oil to Engine
A.
The machine was shipped without oil in the engine.
The engine requires approximately 21 ounces of oil.
B. Use only a clean, high quality detergent oil rated with
the A.P.1. service classification of "SG." Select oil
viscosity grade according to expected temperature when
operating:
• For use at temperatures above 32
0
F, use SAE 30 oil.
• For temperatures below 32
0
F, use SAE 5W30 oil.
NOTE: Although multi-viscosity oils (5W30, 10W30,
etc.), improve starting in cold weather, these multi-
viscosity oils will result in increased oil
consumption when used above 32
0
F. Check your
engine oil level more frequently to avoid possible
engine damage from running low on oil.
C. With the machine on level ground, remove the
dipstick (A, Figure 5) and place it on a clean surface.
D. Using a clean funnel, slowly add oil to the dipstick
hole. While adding oil, frequently reinstall dipstick (screw
dipstick down securely) to check oil level. Wipe dipstick
with a clean cloth before reinserting each time. Fill to the
"FULL" mark on dipstick. DO NOT OVERFILL!
E. Reinstall the dipstick securely.
STEP 4: Check All Nuts and Bolts for Tightness
Check all nuts and bolts for tightness following assembly
and according to the schedule given in the section which
describes "Customer Responsibilities" on Page 27.

NOTE: Change the oil after the first two operating
hours. See "Changing Oil" on Page 23 in the "Customer
Responsibilities" section of this Manual.

NOTE: Do not overtighten the bolts which attach the
engine mounting plate to the housing. DAMAGE TO
THE HOUSING COULD RESULT.
