STEP 4: After the second person has cleared the area, continue lowering the Postmaster
onto the post approximately 24 inches. Gauge this measurement by noting when
the post guide is approximately 6 inches above the first reinforcement plate.
STEP 5: Move the vehicle slowly left, right, forward, or backward as needed until the post
appears vertical to the ground.
STEP 6: The Postmaster can now be activated by turning the auxiliary hydraulics to
the forward position. Drive the post into the ground until the post guide is
approximately 6 inches above the rubber cushion. If needed, shut off the auxiliary
hydraulics and reposition the vehicle to ensure the post is driven into the ground
straight.
STEP 7: Repeat STEPS 4 and 6 until the post has been driven to the desired depth.
STEP 8: Shut off the auxiliary hydraulics, raise the Postmaster until the post is cleared,
and move to the next post.
Once you have become comfortable with the operation of the Postmaster and are driving
posts in straight, you are ready to install your Grapple.
STEP 1: Lower the Postmaster to the ground, and shut off the vehicle.
Operation
(continued)
Failure to lower the Postmaster as the post guide nears the
rubber cushion will result in the hammer bottoming out.
Although occasional bottoming out of the hammer will give
the operator a jolt, it will not (under normal load conditions)
damage the Postmaster. However, repeated bottoming out
of the hammer will cause structural damage and excessive
wear to the Postmaster and vehicle lift arms.

Remember hydraulic systems are under pressure whenever
the engine is running and may hold pressure after
shutdown. Before connecting or disconnecting hydraulic
hoses, be sure to relieve all pressure by cycling all
hydraulic controls after shutdown.
