LUBRICATION
See Figure 15. To reduce wear and assure free movement
of controls, apply light motor oil occasionally at points in­
dicated. Be careful not to get oil on drive belts. Use only
small quantities of oil- Excess oil collects dirt and causes
extra wear. DO NOT OIL SELF-LUBRICATED WHEEL
BEARINGS.
To prevent rust, sand off and paint any parts or areas which
become chipped or damaged. Tighten all bolts, capscrews,
nuts, and fasteners securely.
OFF-SEASON STORAGE
If tiller is to be stored over 30 days proceed as follows:
1. Clean fuel screen and bowl. See Maintenance section of
this manual.
2. Drain fuel tank and lines by placing suitable container
under fuel shut-off valve and opening valve. Store gasoline
in container using a gasoline stabilizer or additive. This
additive prevents formation of gum and varnish for up to
one year.
3. Operate engine until gasoline in carburetor is completely
consumed.
