SAFETY WARNINGS

Cordless Pole Hedge Trimmer Safety Warnings

1. Keep all parts of the body away from the blade. Do not remove cut material or hold material to be cut when blades are moving. Blades continue to move after the switch is turned off. A moment of inattention while operating the hedge trimmer may result in serious personal injury.
2. Carry the hedge trimmer by the handle with the blade stopped and taking care not to operate any power switch. Proper carrying of the hedge trimmer will decrease the risk of inadvertent start-ing and resultant personal injury from the blades.
3. When transporting or storing the hedge trim-mer, always fit the blade cover. Proper handling of the hedge trimmer will decrease the risk of personal injury from the blades.
4. When clearing jammed material or servicing the unit, make sure all power switches are off and the battery pack is removed or disconnected. Unexpected actuation of the hedge trimmer while clearing jammed material or servicing may result in serious personal injury.
5. Hold the hedge trimmer by insulated gripping surfaces only, because the blade may contact hidden wiring. Blades contacting a “live” wire may make exposed metal parts of the hedge trimmer “live” and could give the operator an electric shock.
6. Keep all power cords and cables away from cutting area. Power cords or cables may be hid-den in hedges or bushes and can be accidentally cut by the blade.
7. Do not use the hedge trimmer in bad weather conditions, especially when there is a risk of lightning. This decreases the risk of being struck by lightning.
8. To reduce the risk of electrocution, never use the pole hedge trimmer near any electrical power lines. Contact with or use near power lines may cause serious injury or electric shock result-ing in death.
9. Always use two hands when operating the pole hedge trimmer. Hold the pole hedge trimmer with both hands to avoid loss of control.
10. Always use head protection when operating the pole hedge trimmer overhead. Falling debris can result in serious personal injury.

2. Wear ear protection such as ear muffs to pre-vent hearing loss.
3. Wear protective goggles, safety helmet and protective gloves to protect yourself from flying debris or falling objects.
4. When touching blades or adjusting the blade angle, wear protective gloves. Blades can cut bare hands severely.

Operation

1.  Always use two hands to operate the tool. Using one hand could cause loss of control and result in serious personal injury.
2. While operating the tool, always ensure that the operating position is safe and secure. Overreaching with the tool, particularly from a ladder, is extremely dangerous. Do not work from anything wobbly or infirm.
3. Do not simultaneously wear multiple belt harnesses and/or shoulder harnesses when operating the tool.
4. During operation, keep bystanders or animals at least 15 m (50 ft.) away from the tool. Stop the tool as soon as someone approaches.
5. If cutting tool strikes any object or the tool starts making unusual noise or vibration, switch off the tool and remove the battery cartridge immediately and allow the tool to stop. And then take the following steps:
   • inspect for damage
   • check for, and tighten, any loose parts
   • have any damaged parts replaced or repaired with genuine spare parts.
6. Only use the tool for its intended purpose. Do not use the tool for any other purpose.
7. Switch off the tool and remove the battery cartridge before:
   • cleaning or when clearing a blockage,
   • checking, carrying out maintenance or working on the tool,
   • adjusting the working position of the shear blades,

19. Never point the shear blades to yourself or others.
20. If the blades stop moving due to the stuck of foreign objects between the blades during operation, switch off the tool and remove the battery cartridge, and then remove the foreign objects using tools such as pliers. Removing the foreign objects by hand may cause an injury for the reason that the blades may move in reaction to removing the foreign objects.
21. When attaching or removing the blade cover, be careful not to injure your hands.

• CAUTION : Avoid operating the tool in very hot weather as much as practicable. When operat-ing the tool, be careful of your physical condition.
• CAUTION : Be careful not to accidentally contact a metal fence or other hard objects while trimming. The shear blades may break and cause an injury.
• CAUTION : Be careful not to allow the shear blades to contact the ground. The tool may recoil and cause an injury.
• CAUTION : Overreaching with a hedge trim-mer, particularly from a ladder, is extremely dangerous. Do not work while standing on anything wobbly or infirm.
• NOTICE : Do not attempt to cut branches thicker than 10 mm (3/8″) in diameter with the tool. Cut branches to 10 cm (4″) lower than the cutting height using branch cutters before using the tool.

Pull the switch trigger while pressing the lock-off lever, and then move the tool forward.

For basic operation, tilt the shear blades toward the trimming direction and move it calmly and slowly at the speed rate of 3 to 4 seconds per meter.

To cut a hedge side evenly, cut from the bottom to top.

When trimming to make a round shape (trimming box-wood or rhododendron, etc.), trim from the root to the top for a beautiful finish.

When shearing the grass, apply the shear blades to the grass parallel to the ground, and shear the grass with a right to left swinging movement.

MAINTENANCE

• WARNING : Before inspecting or maintaining the equipment, switch off the motor and remove the battery cartridge. Otherwise, the machine may start unintentionally and result in serious injury.
• WARNING : When inspecting or maintaining the equipment, always put it down. Assembling or adjusting the equipment in an upright position may result in serious injury.
• WARNING : Follow the warnings and precau-tions in the chapter “SAFETY WARNINGS” and the instruction manual of the power unit.
• CAUTION : Wear gloves when performing the inspection or maintenance.
• NOTICE : Never use gasoline, benzine, thinner, alcohol or the like. Discoloration, deformation or cracks may result.

To maintain product SAFETY and RELIABILITY, repairs, any other maintenance or adjustment should be performed by Makita Authorized or Factory Service Centers, always using Makita replacement parts.

Cleaning the tool
