Cutting Unit
Depth Lever
Use the depth lever to raise and lower the blades
between working and transport position. The depth
lever has a lock-out bolt that should be left in until the
blades wear down. Then move the bolt to a lower hole
to allow the blades to penetrate the soil.
Flail Blades or Spring Tines • Set blade or tine
depth so that the blades or tines just touch on a
flat surface such as a sidewalk or driveway.
Delta Blades
• Set blades to penetrate the soil to
a depth of 1 /
8
" to ¼" with a maximum penetration
of ½". Check seed bag for the manufacture’s
recommended depth of application
Lawns with deep thatch exceeding ¾" may be
•
best dethatched in two treatments (spring and
fall) to avoid major shock to an older lawn.
Engine
Refer to your engine manual.
Fueling
Read the safety instructions before fueling.
Keep the fuel and fuel tank clean. Avoid filling the
machine with dirty fuel. Make sure the fuel cap is
properly tightened and the gasket is not damaged,
particularly before washing the machine.
Use unleaded gasoline with minimum 86 octane
rating. Never use gasoline mixed with two-cycle oil.
For ethanol and methanol fuel, the following applies:
Maximum allowable ethanol 10% (volume).
Maximum allowable methanol 5% (volume).
Maximum allowable MTBE (Methyl Tertiary Butyl
Ether) 15% (volume).
If the engine knocks or pings at normal load it can
be damaged. Change the fuel. If this does not help,
contact an authorized service workshop.
Do not fill the tank completely; leave space for the fuel
to expand as it warms up.
Clutch
The clutch tightens the drive belt and engages the
drive for the blades. When the clutch lever is pressed
against the handle, the blades begin to rotate. Hold
the clutch tightly when working so the belt does not
slip.
8060-108
Hold the clutch bail against the upper handle.
WARNING!
Gasoline is highly flammable. Observe
caution and fill the tank outdoors.
See the safety instructions.
