OPERATION
WARNING: Always wear appropriate eye, hearing, hand,
foot and body protection to reduce the risk of injury when
operating this unit. Wear head protection. Use a full face
shield when needed. Refer to the Safety section for
appropriate safety equipment information.
WARNING:
Make sure the chain oil reservoir is full
before operation. Check the oil level constantly so that it
does not drop below half full. Make sure the chain oil
adjustment screw is set appropriately. Refer to Setting the
Chain Oil Adjustment Screw in the Maintenance section.
The saw chain must be continuously coated with oil to
function properly.
WARNING:
Always check the chain tension and adjust as
necessary before beginning operation. Refer to Adjusting the
Chain Tension in the Maintenance section.
TIPS FOR BEST RESULTS
• Follow all safety instructions. Refer to the Safety section.
• Only cut wood and materials made of wood. Do not attempt to
cut sheet metal, plastics, masonry or any other non-wood
materials.
• Practice cutting a few small logs before beginning a major cutting
operation.
• Do not attempt to cut trees or logs with diameters larger than:
- 16 in. / 40.6 cm (TB4620H XP)
IF... the engine fails to start after a few attempts, move the choke
knob to Position 2, press the throttle lockout and squeeze the
throttle control. Pull the starter rope with a controlled and steady
motion 3 to 8 times. The engine should start. If it does not,
repeat this instruction.
IF... the engine is already warm, make sure the On/Off switch is in
the On position, crouch in the starting position, pull the choke
knob out to Position 1 and then push the choke knob back in to
Position 2. Begin the starting procedure with step 13.
PREPARING THE WORK AREA
• Clear the area of children, bystanders and pets; keep them
outside a 50-foot (15 m) radius, at a minimum. Even then, they
are still at risk from thrown objects. Encourage bystanders to
wear eye protection. If you are approached, stop the unit
immediately. When felling, the safe distance is at least twice the
height of the tallest tree in the work area. When bucking, keep
workers at least 15 feet (4.6 m) apart.
• Keep the work area clean. Cluttered areas invite injuries. Do not
start cutting until the work area is clear and free from
obstructions. Make sure there is secure footing and a planned
retreat path from falling trees or branches.
• Do not cut near electrical cables or power lines. Keep at least 50
feet (15 m) away from all power lines.
• Use the unit only in daylight or good artificial light.
