OPERATION
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.
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.
If hydraulic pressure, hydraulic back - pressure, 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.
4Have 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
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.
