OPERATION

PRE-OPERATION PROCEDURES

CHECK THE POWER SOURCE

1.Using a calibrated flowmeter and pressure gauge, check that the hydraulic power source develops a flow of 7–9 gpm/26–34 lpm at 2000 psi/140 bar.

2.Make certain the hydraulic power source is equipped with a relief valve set to open at 2100–2250 psi/140 bar.

INSTALLING ADAPTERS

1.The post hammer is designed to drive No. 1 through No. 4 sign post, 2-1/2 inch square and up to 2-5/8 inch diameter round post without requiring adapters. If you are driving one of these types of post, orient the post into the tightest fit in the post driver foot.

2.If you are driving smaller square or round post, in- sert the adapter to the post driver foot using two ½-hex head capscrews.

CONNECTING HOSES

1.Wipe all hose couplers with a clean, lint-free cloth before making connections.

2.Connect the hoses from the hydraulic power source to the tool fittings or quick disconnects. It is a good practice to connect return hoses first and discon- nect them last to minimize or avoid trapped pressure within the tool.

3.If hose couplers are used, observe the arrow on the coupler to ensure that the flow is in the proper direc- tion. The female coupler on the tool hose is the inlet (pressure) coupler.

4.Move the hydraulic power source On/Off control valve to the ON position to operate the tool.

NOTE:

If uncoupled hoses are left in the sun, pressure in- crease inside the hoses may make them difficult to connect. When possible, connect the free ends of the operating hoses together.

TOOL OPERATION

1.Observe all safety precautions.

2.Install the appropriate adapter as required.

3.Place the post driver foot firmly on the surface to be driven.

4.Press the lever assembly on handle to start the post driver.

NOTE:

On Remote ON/OFF Valve Models Place the post driver on/off control valve in The ON position to start the post driver.

NOTE:

Adequate down pressure is very important.

5.When the post is fully set in the ground, release the lever assembly on handle.

COLD WEATHER OPERATION

If the post hammer is to be used during cold weather, preheat the hydraulic fluid at low engine speed. When using the normally recommended fluid, fluid tempera- ture should be at or above 50°F/10°C (400 ssu/82 cen- tistrokes) before use.

Damage to the hydraulic system or post driver can result from use with fluid that is too viscous or thick.
