Checking and Adding Oil
The engine is shipped without oil in the engine. You must fill the engine
with oil before operating. Running the engine with insufficient oil can
cause serious engine damage and void the product warranty.
1. Place the snow thrower on a flat, level surface.
2. Remove the oil filler cap/dipstick and wipe the dipstick clean. See Figure 7.
NOTE: Do not use synthetic oil for the first five hours of use. Use oil provided.
3. Insert the cap/dipstick into the oil filler neck, but do not screw it in.

ASSEMBLY
4. Remove the oil filler cap/dipstick. If the level is low, slowly add oil until oil
level registers between high (H) and low (L), Figure 8.
NOTE: Do not overfill. Overfilling with oil may cause smoking, hard starting,
or spark plug fouling.
5. Replace and tighten cap/dipstick firmly before starting engine.
NOTE: DO NOT allow oil level to fall below the "L" mark on the dipstick. Doing
so may result in equipment malfunctions or damage.
NOTE: To change the oil in your engine, see the Service and Maintenance
section of this manual.
