4.3.5 — Air Filter Service
The engine will not run properly and may be damaged if
using a dirty air filter. Clean the air filter every 50 hours or
annually (Figure 4-5). Clean or replace more often if
operating under dusty conditions.
1. Remove air filter cover retaining screw and cover.
2. Wash in soapy water. Squeeze filter dry in clean cloth
(DO NOT TWIST).
3. Clean air filter cover before re-installing it.
4. Tighten air filter cover screw securely.

4.3.6 — Valve Clearance Adjustment
• Intake - 0.006 ± 0.0008 in. (0.15 ± 0.02 mm) (cold)
Exhaust - 0.008
± 0.0008 in. (0.20 ± 0.02 mm) (cold)
• After the first 50 hours of operation, check the valve
clearance in the engine and adjust if necessary.
NOTE:
Important: If feeling uncomfortable about doing this
procedure or the proper tools are not available,
please take the generator to the nearest service cen-
ter to have the valve clearance adjusted. This is a
very important step to ensure longest life for the
engine.
To check valve clearance:
1. Make sure the engine is at room temperature
(60 - 80 °F/ 15.55 - 26.66 °C).
2. Make sure that the spark plug wire(s) is removed
from the spark plug and out of the way. Remove
spark plug(s).
3. Remove the six screws attaching the valve cover(s).
4. Make sure the piston is at Top Dead Center (TDC) of
its compression stroke (both valves closed). To get
the piston at TDC, pull the recoil handle slowly while
watching the piston through the spark plug hole. The
piston should move up and down. The piston is at
TDC when it is up as high as it can go.
