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
WARNING
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.

OPERATION
PRE-INSTALLATION INSTRUCTIONS
SKIDSTEER, BACKHOE OR EXCAVATOR SIZE
Check the Specifications section of this manual to
determine correct carrier size, hydraulic ow and pressure
requirements.
If hydraulic pressure, hydraulic back-pressure,
hydraulic ow 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 ttings. 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 specied capacity and pressure ratings.
2. Be sure the uid in the hydraulic system is clean.
3. Check the hydraulic lter. Replace the lter 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 specied ow and pressure rating for the
breaker. See the Specications section of this manual.
HYDRAULICS
Some carriers may have ows above or below ow and
pressure ranges required. Refer to Flow and Pressure
Specications on page 17 of this manual. If the ow is lower
the drop hammer will simply cycle at a slower rate. If the ow
rate is higher the control valve on the drop hammer will limit
the ow to prevent the chain over-speeding and catching the
weight as it drops.
