tighten. Do not use excessive force.

REPLACING THE SPARK PLUG

Use a type RDJ8J spark plug (or equivalent ). The cor-

every 50 hours of operation and check its condition.
1. Stop the engine and allow it to cool. Grasp the plug
wire firmly and pull the cap from the spark plug.
2. Remove any dirt from around the thread. Remove
the spark plug from the cylinder using a 5/8 in. spark
plug wrench and turning it counterclockwise.
3. Replace cracked, fouled or dirty spark plugs. Set the
air gap at 0.5 mm (0.020 in) using a feeler gauge
(Fig. 27).
4. Install a correctly gapped spark plug in the cylinder
head . Tighten the spark plug using a 5/8 in. spark
plug wrench and turning it clockwise until snug. Do
not over-tighten.
If using a torque wrench, torque to 12.3-13.5 Nm
(110-120 in.lb).
