OIl Injection System
OIL INJECTION FILTER
IMPORTANT: The oil injection in‑line filter must be replaced after the first 100
hours of operation. Afterwards, this filter must be replaced every 300 hours of
operation. After replacing the in‑line filter, the oil injection system must be
purged to remove air trapped in the system.
1. Cut the cable ties securing the in‑line oil filter.
2. Place an appropriate container or shop towels under the in‑line filter to
capture oil that will leak out of the hoses.
IMPORTANT: The arrow on the filter identifies the direction of the oil flow and
should point towards the oil pump.
3. Quickly remove the old filter and install a new filter.
