MAINTENANCE
LONG-TERM STORAGE
For storage of the trowel for over 30 days, the following is
required:
Drain the fuel tank completely, or add STA-BIL to the fuel.
Run the engine until the gasoline in the carburetor is
completely consumed.
Completely drain the oil from the crankcase and refill
with fresh oil.
Remove the spark plug. Pour 5 to 10 cc of SAE 30 oil
into the cylinder. Turn the engine switch to the
START
position for a few seconds to distribute the oil. Reinstall
the spark plug.
Clean all external parts of the trowel with a cloth.
Cover the trowel and store in a clean, dry place.
12. Reinstall square head cone point into spider plate and
tighten in place. Tighten jam nut. Use care in making
sure point of set screw engages groove in gear box
main shaft.
13. Lubricate all grease points (zerk fittings) with premium
"Lithum 12" based grease, conforming to NLGI Grade
#2 consistency.
INSTALLING PANS ONTO FINISHER BLADES
These round discs, sometimes referred to as "pans", attach
to the spiders arms and allow early floating on wet concrete
and easy movement from wet to dry areas. They are also
very effective in embedding large aggregates and surface
hardeners.
Refer to Figure 61 when installing pans onto finisher blades.
Figure 61. Z-Clip Finisher Pan Installation
1. Lift trowel just enough to slide pan under blades. Lower
finisher onto pan with blades adjacent to Z-Clips.
2. Rotate blades into position under Z-Clips. Ensure that
the blades are rotated in the direction of travel when
the machine is in operation or use the engine to rotate
the blades into position.
3. Attach the blade tie-downs to the far side of the Z-Clip
brackets with tie-down knobs as shown in Figure 61.
4. Check to make certain that the blade edges are
secured under the Z-Clips and the tie-downs are
secured completely over the edges of the blade bar
before the machine is put back into operation.
