PRE-INSTALLATION INSTRUCTIONS

SKIDSTEER, BACKHOE OR EXCAVATOR SIZE

Check the Specifications section of this manual to
determine correct carrier size, hydraulic flow and pressure
requirements.
I f h y d r a u l i c p r e s s u r e , h y d r a u l i c b a c k - p r e s s u r e ,
hydraulic flow or excavator weight class are exceeded, the
drop hammer warranty is void.
Do not use bare hands to check or search for hydraulic
leaks around hoses and fittings. Pinhole leaks can
penetrate the skin. To inspect for leaks, depressurize
the system, clean around suspected area, repressurize
the system and visually check for leaks.

TEST THE HYDRAULIC SYSTEM

1. Have your Stanley dealer test the carrier hydraulic
system to make sure the system is operating at the
manufacturers specified capacity and pressure ratings.
2. Be sure the fluid in the hydraulic system is clean.
3. Check the hydraulic filter. Replace the filter if dirty or
deteriorated.
4 Have your Stanley dealer test the circuit to which the
breaker will be connected to make sure that the circuit is
supplying the specified flow and pressure rating for the
breaker. See the Specifications section of this manual.

HYDRAULICS

Some carriers may have flows above or below flow and
pressure ranges required. Refer to Flow and Pressure
Specifications on page 17 of this manual. If the flow is lower
the drop hammer will simply cycle at a slower rate. If the flow
rate is higher the control valve on the drop hammer will limit
the flow to prevent the chain over-speeding and catching the
weight as it drops.
10 DH USER MANUAL

OPERATION

Before connecting the drop hammer to the carrier hydraulic
system; it is important to determine which are the pressure and
tank lines of the carrier and connect the hoses appropriately.
The pressure and tank lines are marked where they enter the
valve block. If the hydraulics are connected incorrectly, the
motor will rotate in the wrong direction. This will not damage
the machine but it will not lift.

TOOL INSTALLATION

Do not lift or transport the drop hammer without the
travel lock installed.
The hammer can move freely in the housing if the
travel lock is not installed which can result in serious
injury or death.
Ensure travel lock is installed.
The drop hammer may be lifted with a forklift through the
mounting bracket or by feeding chains through the points
shown in Figure 1 below. Always lift the drop hammer with
machinery and lifting equipment that is rated to carry the
weight of the machine.
