Maintenance and Troubleshooting
4. See Figure 4-4. Measure spark plug electrode gap
(C) with a suitable gauge. The gap should be
0.028–0.031 in (0.70–0.80 mm). Correct the gap, if
necessary, by carefully bending the side electrode.
Figure 4-4. Spark Plug Electrode Gap
5. Install spark plug carefully by hand, to avoid cross-
threading.
6. Tighten spark plug to compress the water after the
spark plug seats.
• If installing a used spark plug, tighten 1/8–1/4 turn
after spark plug seats.
• If installing a new spark plug, tighten one half turn
after spark plug seats.
NOTE: Overtightening the spark plug can damage
threads in the cylinder head. Undertightening the spark
plug can overheat and damage the engine.
7. Install the spark plug cap.
Checking the Hydraulic Fluid Level
1. Verify unit is on a flat, level surface.
2. Remove reservoir dipstick from reservoir tank and
clean with a clean, lint free cloth.
3. Replace dipstick and push down completely for an
accurate reading.
4. Remove dipstick and check fluid level. Proper level
is approximately 0.25 in (6.4 mm) above the bot-
tom of the dipstick.
5. Add fluid as needed until fluid is at proper level.
Changing the Hydraulic Fluid
Draining Head End of Cylinder
1. Remove spark plug wire and spark plug to reduce
back pressure on engine and to prevent accidental
startup.
2. See Figure 4-5. Place a suitable waste fluid con-
tainer below oil return hose (A).
Figure 4-5. Pump Assembly
3. Disconnect oil return hose from oil reservoir (B).
Position oil return hose into the waste fluid con-
tainer.
4. Extend the cylinder by holding the hydraulic control
valve handle forward and have an assistant pull on
engine’s pull start cord until fluid from oil return
hose stops flowing.
5. Properly dispose of waste hydraulic fluid per local
or state regulations.
Draining the Hydraulic Tank
1. See Figure 4-5. Position suitable waste fluid con-
tainer under oil suction hose (C).
2. Loosen hose clamp (D) securing oil suction hose to
bottom of the pump.
3. Remove hose end from pump and place into waste
fluid container.
4. Lower the front of unit slightly by folding the jack
stand to completely drain tank.
5. Connect oil suction hose to pump and secure hose
clamp when draining is complete.
Refilling the Hydraulic Tank
NOTE: See Adding Hydraulic Fluid for recommended
hydraulic fluid types.
1. Remove reservoir dipstick and fill tank with recom-
mended hydraulic fluid until it reaches the initial fill
line on dipstick.
2. Install dipstick when fluid has reached proper level.
Draining and Refilling Piston End of Cylinder
1. Position oil return hose into a waste fluid container.
2. Hold the control handle in reverse and pull engine
pull start cord until rod is fully retracted to drain pis-
ton end of cylinder.
3. Inspect o-ring (11 mm x 2 mm) on oil reservoir for
damage. Replace if damaged or missing.
