Operation - Greenlee H4910A Instruction Manual

Operation

Electric shock hazard:
This tool is not insulated. When
using this unit near energized
electrical lines, use only certified
nonconductive hoses and proper
personal protective equipment.
Failure to observe this warning
could result in severe injury or death.
Pinch points:
Keep hands away from moving parts
during operation.
Do not disconnect tool, hoses, or fittings while the
power source is running or if the hydraulic fluid is
hot. Hot hydraulic fluid can cause serious burns.
• Support or secure pole that is being removed. An
unsecured pole can fall.
• Use only 5/8" alloy chains that have a minimum
working load limit of 9071 kg (20,000 lb). Other
chains can break during operation.
• Do not change accessories, inspect, adjust, or
clean tool when it is connected to a power source.
Accidental startup can result in serious injury.
Failure to observe these warnings could result in
severe injury or death.

Pre-Operation
Refer to the "Identification" section and the Hydraulic
Schematic under "Specifications."
1. Stop the power source.
2. Connect hydraulic hoses from control valve to pole
puller. Refer to "Hose Connections." Start power
source.
3. It is recommended that power source be allowed
to run (idle) for a few minutes to warm hydraulic
reservoir fluid. Actuating tool intermittently will
reduce the time required to warm fluid to an efficient
operating temperature.
4. Cycle tool full stroke to remove any trapped air from
tool and hoses. Stop power source. Check hydraulic
fluid level in power source reservoir.
Operation
Refer to the "Identification" section.
1. Pole that is to be removed must be supported or
secured before and while pulling pole from ground.
2. Place pole puller base (2) next to pole that is to be
pulled, preferably on level ground. Set pole puller
cylinder (1) on base.
3. Attach upper chain (3) by placing large loop over
upper chain lug (5) of pole cylinder (1). Loop chain
around pole and hook chain into upper lug. Allow
some chain slack to permit puller to slide down pole
after it completes pulling stroke.
4. Attach lower chain (4) by hooking one end of chain
into one lower chain lug (6), looping chain around
pole and hooking chain into opposite lower chain
lug (6).
5. Start power source, and actuate pole puller as many
times as necessary to remove pole.
Note: Chains may need to be adjusted as pole
diameter increases. Stop power source before
adjusting chains.
6. Stop power source. Remove upper and lower
chains from pole.
