IMPORTANT: Do not remove the vent cap from the engine‑mounted oil
reservoir tank when filling the tank. Removal of the vent cap may damage the
threads in the oil reservoir tank. Damaged threads may result in future oil
leakage.
2. Check the oil level in the engine‑mounted oil reservoir tank. The tank
must contain at least 118 ml (4 oz) of oil prior to starting the engine.
3. If the oil level is less than 118 ml (4 oz), loosen the vent cap. Use a squirt
can and fill the tank with at least 118 ml (4 oz) of the recommended oil.
