PREPARATON PROCEDURES
PREPARATION FOR INITIAL USE
Each unit as shipped has no special unpacking or
assembly requirements prior to usage. Inspection to
assure the unit was not damaged in shipping and does
not contain packing debris is all that is required.
CHECK HYDRAULIC POWER SOURCE
1.
Using a calibrated flowmeter and pressure gauge,
check that the hydraulic power source develops a
flow of 7–10 gpm/26–38 lpm at 2000 psi/105–140
bar.
2.
Make certain the hydraulic power source is equipped
with a relief valve set to open at 2100–2250 psi/145–
155 bar minimum.
3. Check that the hydraulic circuit matches the tool for
open-center (OC) operation.
CHECK TOOL
1.
Make sure all tool accessories are correctly installed.
Failure to install tool accessories prop erly can result
in damage to the tool or personal injury.
2.
There should be no signs of leaks.
3. The tool should be clean, with all fittings and
fasteners tight.
CHECK TRIGGER MECHANISM
1.
Check that the trigger operates smoothly and is free
to travel between the
ON
and
OFF
positions.
CONNECT 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 hose couplers on the spike driver. Connect the
return hose first and disconnect it last to minimize or
avoid trapped pressure within the spike driver.
3. Observe flow indicators stamped on hose couplers
to be sure that oil will flow in the proper direction.
The female coupler is the inlet coupler.
NOTE: Uncoupled hoses left in the sun may be
difficult to connect. When possible, connect the free
ends of operating hoses together.
OPERATING PROCEDURES
1. Observe all safety precautions.
2. Move the hydraulic circuit control valve to the
ON
position.
3. Place the spike driver foot firmly on the spike to be
driven.
4.
Squeeze the trigger to start the spike driver.
Adequate down pressure is very important. When
the spike fully sets in the tie, release the trigger.
NOTE: Partially depressing the trigger allows the
tool to operate at a slow speed, making it easy to
start the spike in the tie.
COLD WEATHER OPERATION
If the spike driver is to be used during cold weather,
preheat the hydraulic fluid at low engine speed.
When using the normally recommended fluids, fluid
temperature should be at or above 50 °F/10 °C (400
ssu/82 centistokes) before use.
