SAFETY PRECAUTIONS
POLE CHAIN SAW SPECIFIC SAFETY PRECAUTIONS
• Do not rely exclusively upon the safety devices built into the saw.As a pole saw user, several steps must be taken to keep
your cutting jobs free from accident or injury.
• With basic understanding of kickback, you can reduce or eliminate the element of surprise. Sudden surprise contributes
to accidents.
• Keep a good firm grip on the pole chain saw with both hands. Place your right hand on the rear handle and your left hand
on the outer tube assembly when operating. Use a firm grip with your thumbs and fingers encircling the chain saw handle
and outer tube assembly. A firm grip helps reduce kickback and maintains control of the pole chain saw. Do not let go.
• Make sure the area in which you are cutting is free of obstructions. Never allow the nose of the guide bar to contact a
branch or any other obstruction that can be accidently hit while operating the saw.
• Follow the manufacturer’s sharpening and maintenance instructions for the saw chain.
• Only use replacement bars and chains specified by Kubota or equivalent.
• Make sure you’re well rested and mentally alert before operating the pole chain saw.
• Do not start cutting until you have a clear work area, secure footing and a planned drop area for falling branches.
• Keep all parts of the body away from the saw chain during operation.
• Carry the saw with the unit de-energized.
• Do not operate a pole chain saw that is damaged, improperly adjusted or not completely and securely assembled. Make
sure the chain stops moving when the control trigger is released.
• Use extreme caution when cutting small branches. Twigs may catch the saw chain and be whipped toward the operator
or pull the operator off balance.
• When cutting a limb that is under tension, be aware of spring-back so you will not be struck when the tension on the limb
is released. Always cut on the outside arc or curve.
• Keep the handle dry, clean and free of hydraulic fluid.
• When using tools near energized transmission lines, make sure to use only hoses labeled and certified non-conductive.
• Turn off the power unit or move the hydraulic control valve to neutral before setting the pole chain saw down.
• Use a chain bar scabbard when transporting the saw.
• Know the location of buried or covered electrical services before starting work.
• To avoid personal injury or equipment damage, all tool repair, maintenance and service must only be performed by
authorized and properly trained personnel.
• Supply hoses must have a minimum working pressure rating of 2500 psi/175 bar. Refer to the Tool Hose Section in this
manual.

The following guidelines must be followed to prevent accidental contact with overhead electrical conductors and/or
communication wires and cables. (ref. ANSI Z133.1-1982).
All overhead conductors and all communications wires and cables are considered to be energized with potentially
fatalvoltagesandmustneverbetouchedeitherdirectlyorindirectly.Accidentalcontactwithanyoverheadconductorsor
communication wires and cables can result in death or serious injury.
1. A close inspection shall be made by the tool operator and by the tool operator’s supervisor to determine whether an
electrical conductor passes through the tree or passes within reaching distance of the tool operator.
2. Only qualified tool operators shall be assigned to the work if an electrical hazard exists.
3. A second qualified tool operator must be within normal voice communication during line clearing operations aloft when
the tool operator approaches closer than 10 feet (3m) to any conductor or electrical apparatus energized in excess of 750
volts, or when roping is required to remove the branches or limbs.
4. Tool operators must maintain the following clearances from energized conductors:
Voltage Range
(phase-to-phase) (kV) Minimum Working Distance
2.1 to 15.0 2 ft 0 inches / 0.6 meters
15.1 to 35.0 2 ft 4 inches / 0.7 meters
35.1 to 46.0 2 ft 6 inches / 0.75 meters
46.1 to 72.5 3 ft 0 inches / 0.9 meters
72.6 to 121.0 3 ft 4 inches / 1.0 meters
138.0 to 145.0 3 ft 6 inches / 1.05 meters
161.0 to 169.0 3 ft 8 inches / 1.1 meters
230.0 to 242.0 5 ft 0 inches / 1.5 meters
345.0 to 362.0 7 ft 0 inches / 2.1 meters
500.0 to 552.0 11 ft 0 inches / 3.35 meters
700.0 to 765.0 15 ft 0 inches / 4.55 meters
All other tree workers must maintain a minimum clearance of 10 feet (3 meters) from energized conductors rated 50 kV
phase-to-phase or less. Conductors rated over 50 kV phase-to-phase require a minimum clearance of 10 feet plus 4/10 of
an inch (3 meters plus 10 mm) for each kilovolt over 50 kV.
5. When a lifting device contacts an electrical conductor, the truck supporting the device is considered to be energized and
contact with the truck must be avoided except when emergency rescue procedures are being carried out. Emergency rescue
should only be attempted by properly trained personnel familiar with electrical hazards.
6. Storm work and emergency conditions create special hazards. During these conditions, only authorized tool operators
shall perform any tree operation.

VENTILATE WORK AREA
•If the engine must be running to do some work, make
sure the area is well ventilated. Never run the engine in
a closed area. The exhaust gas contains poisonous
carbon monoxide.
PREVENT ACID BURNS
• Sulfuric acid in battery electrolyte is poisonous. It is
strong enough to burn skin, clothing and cause blindness
if splashed into eyes. Keep electrolyte away from eyes,
handsandclothing.Ifyouspillelectrolyte on yourself, flush
with water and get medical attention immediately.
DISPOSE OF FLUIDS PROPERLY
• Do not pour fluids into the ground, down a drain or into
