SAFETY
MANEUVERING SAFELY
In general
- Slow down before turning.
- Be aware when approaching blind corners,
shrubs, trees, tall grass or other objects that may
obscure vision.
WARNING
Slope Operation
- Slopes are a major factor in loss-of-control and
tip over accidents that sometimes lead to severe
injury or death. All slopes require extra caution.
- Before operating on slopes, evaluate the risks
involved.
- Do not operate on slopes if uneasy or uncertain.
Ultimate responsibility for safe operation on
slopes rests with the operator.
- Do not operate steep slopes.
A slope is too steep if:
- The machine must be crabbed (turned partially
sideways uphill) to drive across the slope.
- The machine turns downhill going across the
slope.
- You are uneasy about being on the slope
- With walk behind machines, operate across
slopes, not up and down.
- Avoid starting or stopping on a slope. If wheels
lose traction, disengage the traction clutch and
proceed slowly straight down the slope.
- Keep all movement on the slopes slow and
gradual. Do not make sudden changes in speed
or direction.
- Do not turn on slopes unless necessary, and then
turn slowly and downhill when possible.
- Do not operate near dropoffs, ditches or
embankments. The machine could suddenly turn
over if a wheel runs over the edge or an edge
caves in.
- Follow the manufacturer's recommendations
for wheel weights or counterweights to improve
stability.
MAINTENANCE AND STORAGE SAFETY
In general
- Maintain machine according to manufacturer's
schedule and instructions for maximum safety
and best results.
- Park machine on level ground.
- Never allow untrained personnel to service machine.
- Guards should only be removed by a qualied
technician for maintenance or service. Replace
when work is complete.
- Adjust or repair only after the engine has been
stopped and the tines have quit rotating.
- Replace parts if worn, damaged or faulty.
For best results, always replace with parts
recommended by the manufacturer.
- Disconnect spark plug wire(s) before making any
repairs.
- Do not dismantle the machine without releasing
or restraining forces which may cause parts to
move suddenly.
- Provide adequate support, e.g. jackstands for
lifted machine or parts if working beneath.
- Do not put hands or feet near or under rotating
parts.
- Clean up spilled oil or fuel thoroughly.
- Replace faulty mufers.
- To reduce re hazards, keep the engine, mufer, and fuel storage area free of grass, leaves,
debris buildup or grease.

Tines
WARNING
- Tines are sharp and can
cut. Use extra caution when
handling. Wear appropriate
personal protective equipment.
- Only replace tines. Never
straighten or weld them.
- Keep other persons away
from tines.
WARNING
Fuel
- Petrol (Gasoline) and
diesel fuels are ammable;
petrol (gasoline) vapors are explosive. Use extra
care when handling.
- Store only in containers specically designed for
fuel.
- When refueling or checking fuel level:
- Stop the engine and allow to cool;
- Do not smoke;
- Refuel outdoors only;
- Use a funnel;
- Do not overll;
- If fuel is spilled, do not attempt to start the
engine until the spill is cleaned up and vapors
have cleared.
- Replace caps on fuel containers and tanks
securely.
Sparks from static electricity can start res or cause
explosions. Flowing fuel can generate static electricity. To prevent static electricity sparks:
- Keep fuel containers electrically grounded.
- Do not ll containers in a vehicle or on a truck or
trailer bed with a plastic liner. Fill containers on
the ground away from the vehicle.
- When practical, remove gas powered equipment from the truck or trailer and refuel it on the
ground. If equipment must be refueled on the
truck or trailer, refuel from a portable container
rather than a dispenser nozzle.
- Keep the dispenser nozzle in contact with the rim
of the fuel tank or container opening until fueling
is complete. Do not use a nozzle lock-open
device.
Storage
- Stop the engine and allow to cool before storing
- Drain the fuel tank outdoors only.
- Store fuel in an approved container in a cool, dry
place
- Keep the machine and fuel containers in a locked
storage place to prevent tampering and to keep
children from playing with them.
- Do not store the machine or fuel container near
appliances with an open ame such as a water
heater or other appliance with a pilot light.
- Keep petrol (gasoline) storage area free of grass,
leaves and excessive grease to reduce re hazard.
- Clean grass and debris from cutting units, drives,
mufers and engine to help prevent res.
