Never point the hose at bystanders.
PREOPERATION PROCEDURES
CHECK POWER SOURCE
1. Each sinker drill has been assembled before
leaving the factory, so it is necessary to check
whether there is any damage caused in the
shipping process or whether there is debris
2. entrained in the assembly when the first use
3. Using a calibrated flow meter and pressure gauge,
make sure the hydraulic power source develops a
flow of 20 Ipm at 155 bar.
4. Make certain that the power source is equipped with
a relief valve set to open at 2100-2250 psi/145-155
bar maximum.
5. Make certain that the power source return pressure
CHECK TOOLS
1. Make sure all tool parts are properly assembled
2. Make sure There was no oil leak
3. Make sure all assemblies must be clean and all
acc
essories and interfaces must be securely
assembled
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 couplers on the sinker drill.
3. Observe the arrow on the couplers to ensure the
flow is in the proper direction.
3. Focus on the object you plan to work on.
4.Put the hydraulic control valve in the "ON".
5.Turn on the hydraulic power source to start
operation.
6.When operating, first turn the knob switch to 0
position, and then punch a small pit on the working
surface to facilitate the positioning of the drill bit.
7.Adjust the know switch to appropriate level (1-3) for
working.
COLD WEATHER OPERATION
If the tool 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.
Drill deep holes for operation
1. When the depth of the drilling hole is more than 1
meter, an external air source is required for
operation. An external air source pipe is inserted at the
lower inlet hole..
NOTE:
If uncoupled hoses are left in the sun, pressure in-
crease inside the hoses might make them difficult to
connect. Whenever possible, connect the free ends
of the hoses together.
OPERATION
1. Observe all safety precautions.
2. Connect hydraulic hose, clean coupler before
connection.
