Description

The Greenlee Utility 43180 Circular Saw is intended for

general tree trimming from the ground or from an aerial

device. A rugged, direct-drive motor provides enough power for the 9" diameter blade to cut branches up to 89 mm (3-1/2") in a single pass. The angled head allows ush cuts while directing saw chips away from the operator. The long-reach pole allows cutting in areas

that shorter tools cannot reach.

Flying debris hazard:

Do not use this saw for cutting or clearing at ground

level. If the blade contacts the ground or other solid

object, the operator can lose control of the saw and

the blade can shatter. Operator can be injured by

ying debris.

Failure to observe this warning could result in severe

injury or death.

The patented Super Spool™ design allows the tool to be used with either open-center or closed-center hydraulic systems. The dielectric property of the berglass pole reduces the chance of an electric shock when the saw is used near energized electrical line. Other features include a hand-stop safety collar, a safety trigger, and a trigger guard.

All specications are nominal and may change as design improvements occur. Greenlee Textron Inc. shall not be liable for damages resulting from misapplication or misuse of its products.

Operation

43180 Overhead Circular Saw

Electric shock hazard:

• This tool was tested to meet OSHA

1910.269 (dry test) when manufac-

tured. It must be properly cleaned and maintained to ensure contin-

ued non-conductive properties. When using this unit near energized electrical lines, use only certied non-conductive hoses and proper personal protective equipment.

• Keep berglass extension clean and dry when working around energized

electrical lines.

Accumulated oil, dirt, and moisture

increase the conductive properties of the tool.

Failure to observe these warnings

could result in severe injury or death.

Do not disconnect tool, hoses, or ttings while the power source is running or if the hydraulic uid is hot. Hot hydraulic uid could cause serious burns.

Do not change accessories, inspect, adjust, or clean tool when it is connected to a power source. Accidental start-up can result in serious injury.

Failure to observe this warning could result in severe

injury or death.

The saw blade continues to rotate after the trigger is released. Do not retract or lay the saw down until

blade stops moving.

Failure to observe this warning could result in severe

injury or death.

Do not use this saw for cutting or clearing at ground

level. If the blade contacts the ground or other solid

object, the operator can lose control of the saw and

the blade can shatter. Operator can be injured by

ying debris. Failure to observe this warning could result in severe

injury or death.

Emergency stop procedure:

1. Release the control lever.

2. Shut off the hydraulic power source.

Pre-Operation

Refer to the “Identication” section.

1. Stop power source.

2. Hand stop (6) must be positioned between saw head (8) and your hand on ﬁberglass extension (5), preferably located 35" from trigger handle (2).

3. Connect hydraulic hoses from power source to tool. Start power source.

4. It is recommended that power source be allowed to run (idle) for a few minutes to warm hydraulic reservoir uid. Actuating tool intermittently will reduce time required to warm uid to an efcient operating

temperature.

5. Always operate newly mounted blades on saw

for one minute to ensure proper blade application before cutting any material.

Operation

Refer to the “Identication” section.

1. Grasp berglass extension (5) with one hand and trigger handle (2) with your opposite hand.

2. Position saw in approximate area to make the

desired cut.

3. To start saw, move trigger interlock latch (3) and press (squeeze) trigger (4).

4. Feed rotating blade into work using a straight, steady, constant pressure. Do not “bump”, jam, or

force blade into work, or twist blade in saw cut.

5. Feed blade through work as fast as possible without slowing blade in cut. Blades operated at speeds signicantly below efcient speed or if fed through cut too slowly will generate excessive heat, resulting in rapid blade wear and/or blade breakage.

6. To stop saw, release trigger (4).

7. After blade has stopped rotating, lay saw on a at surface or hang up saw using hook (7).

8. Hook (7) may be used to assist in clearing cut

branches only if blade is not rotating.
