3-4. HAMMER COMPONENT DESCRIPTION
1. BACKHEAD
The backhead connects the hammer to the drill rod. It is threaded into the top end of the
wearsleeve with a large cross section thread form and into the drill rod with a standard REG.
API thread. Other threads are available upon request.
2. CHECK VALVE
The check valve maintains pressure in the hammer when the air supply has been shut off.
The pressure in the hammer balances the hydrostatic pressure in the hole thereby preventing
contaminants from entering the hammer.
3. CHECK VALVE SPRING
The check valve spring provides tension under the check valve to keep it closed.
It is compressed as the air is turned on.
4. AIR DISTRIBUTOR
The air distributor locating on the top of cylinder and guides the check valve and the check valve
spring.
The air distributor plays a role for hammering and flushing with distributing air from the check valve
into the cylinder & piston.
5. CYLINDER
The cylinder is cylinder shaped inside wearsleeve, structures air flow for cycling of piston, with
complex holes at upper & lower part.

Chang Shin
[ 9 ]
int'l co., ltd.
6. PISTON
The piston functions as the only moving part in the hammer, controlling the operational air cycle.
The percussive action of the piston striking the bit transfers the energy through the bit in order to
fracture rock formation.
7. WEARSLEEVE
The wearsleeve is designed to contain the internal parts which make up the hammer assembly.
The wearsleeve is hardened to extend life in abrasive conditions.
8. PISTON STOP RING
The piston stop ring is a hardened steel ring installed in the chuck end of the wearsleeve.
The piston stop ring is prevents the piston from falling out when the chuck , the bit retaining
rings and the bit are removed.
9. BIT RETAINING RING
The bit retaining ring are designed to allow the bit to move between the drilling and cleaning
positions and prevent the bit from coming completely out of the hammer.
The bit retaining ring consist of two matched halves and are held together with an "O" ring.
10. CHUCK
The chuck threads into the bottom of the wearsleeve with a large cross section thread form.
It has internal splines that mesh with the splines on the bit body to transmit rotation.

3-5. ASSEMBLY
Assembly should be performed in a clean environment.
All parts should be cleaned thoroughly and wiped dry before assembly.
Oil all parts by hand using Rock Drill Oil to insure easy assembly.
Coat all thread connections with a thread compound to allow joints to screw freely.
1. Stand the wearsleeve on the floor, chuck end upwards.
2. Insert the piston stop ring into the bore of wearsleeve. piston stop ring is positioned in the correct grooves for
the particular chuck conversion.
3. Coat the piston with rock drill oil and slide it into the backhead end of the wearsleeve.
(ensure the piston striking face enters first.)
4. assemble air distributor and cylinder then push the assembly into the backhead end of the wearsleeve.
5. Slide the buffer ring on to the air distributor
. Insert the spring into the check valve, and then slide the assembly into the air distributor upper bore.
push the whole assembly down onto the buffer ring.
7. Fit a "o" ring to the backhead and coat the threads in copper based thread grease.
Screw the backhead into the wearsleeve until it is hand tight
8. Place the bit retaining ring "o" ring around the bit retaining ring and place in the chuck end of wearsleeve.
9. Thread the chuck into the wearsleeve and hand tighten.
Mind your fingers!
Keep your clothing, hair etc.
Carelessness can result in serious injury.

4. MAINTENANCE
4-1. DISASSEMBLY
- If at all possible, the backhead and chuck should be broken loose on the drill rig;
this is much easier than trying to do so after the drill has been removed from the drill rig.
- Maintenance should be performed in a clean environment.
- Tools needed: overhead crane, hammer stand, chain vise, brass rod, snap ring pliers, press,
a drift pin and a small screwdriver.
- Clean the outside of the hammer. This will insure a good surface to clamp on.
- Using an overhead crane, place the hammer horizontally on a hammer stand and secure the hammer
with a chain vise. Place the chain vise on the area of the wearsleeve where the piston stop ring is
housed when working on the chuck end of the hammer. When working on the backhead end of the
hammer, place the chain vise on the area of the wearsleeve where the check valve housing is housed.
- Unscrew and remove the backhead from the wearsleeve. Remove the backhead "o"ring from
the backhead.
- Remove the check valve, the check valve spring from the backhead end of the wearsleeve.
- Remove the buffer ring from the top of the air distributor.
- Unscrew and remove the chuck, bit and the bit retaining rings from the wearsleeve.
- Remove the bit retaining rings "o"ring from the bit retaining rings.
- Using a brass rod, slide the piston against the air distributor and push the cylinder out the backhead
end of the wearsleeve.
- Slide the piston out the backhead end of the wearsleeve.
- Removal of the spacer and piston stop ring is not necessary for routine maintenance. If necessary,
use a press, apply pressure to the brass rod and force the piston stop ring press plate and the piston
stop ring out of the chuck end of the wearsleeve.

4-2. INSPECTION
- All parts should be washed in a cleaning solvent before they are inspected and reassembled.
- Handle all part carefully, hardened parts may chip if dropped on a hard surface.
BACKHEAD
- Inspect the threads for cracks and burrs.
- Remove all burrs on the thread area with a fine file.
- Replace if necessary.
CHECK VALVE
- The check valve should be smooth and free from abrasions.
- Replace if necessary.
- Replace the check valve spring if it is worn or broken.
AIR DISTRIBUTOR
- Inspect the outside diameter for nick, burrs and scoring.
- Inspect all make up surfaces for indentations or nicks caused by wear.
- Remove all minor irregularities with emery cloth.
- Replace if necessary.
PISTON
- Inspect the striking face, inside and outside diameters for nicks, scoring and cracks.
- Polish the piston with emery cloth to remove all minor irregularities, cracked pistons should be replaced.
- Wash the piston throughly, inside and out, to remove all emery dust.
WEAR SLEEVE
- Inspect the outside diameter for excessive wear or cracks. Inspect the internal case bore for scoring.
- Remove all minor irregularities with fine honing stones.
CHUCK
- Inspect for cracks and burrs.
- For continued use, the outside diameter should be larger than the outside of the ware sleeve or the same.

4-3. LUBRICATION
Inadequate supply of the correct type of oil is a major contributor to excessive component wear and consequently, a
rapid fall off in performance.
An air line lubrication should be installed, preferably on the drill rig. This should be of sufficient capacity to supply the
required volume of oil for a full shift.
The lubrication must be adjustable and set to ensure the correct flow of oil required by the hammer.
The amount of lubricating oil will vary the operating pressure and volume of air used by the hammer.
As a general guide, any CS POWER hammer will require 1/3 rd of a pint per hour 100 CFM through the hammer
(0.07 ltr per 1.0 M
³
/min) per hour.
When drilling with foam or water, the amount of lubricating oil should be increased by 50%.
When new drilltubes are put into use, it is recommended that 1/2 a pint of oil (0.25 ltrs) be poured into each new
tube to give them a good coating of oil and to prevent the hammer from running dry at any time.
Ambient temperatures will determine the grade of Rock Drill oil to be used. Should the ambient temperature be
between 225-325OF, use a 30 grade oil. When the ambient temperature is over 325OF, use a 50 grade oil.
A selection of recommended Rock Drill oils suitable for CS POWER hammers is given below.

4-4. STORAGE
When storing a CS POWER Hammer it is important to take the necessary steps in order to insure a smooth operation after
restarting.
When the hole is completed and the hammer is to be inactive for several weeks or longer the following steps should be followed.
Each drill rod should be blown clear of all water. During this process, turn on the in line lubricator and blow until the rock drill oil
can be seen from the bottom end of each drill rod. In addition, each rod (pin and box end) should be wiped clean and capped to
prevent foreign contaminants from sticking to the connector end.
▣
SHORT TERM STORAGE
When the CS POWER hammers will be stored for only a short period of time the following steps should be taken:
- Blow the hammer clear of all water.
- Pour 1 quart (1 liter) of rock drill oil into the backhead.
- Turn the air on and cycle for 10 seconds. This will lubricate the internal parts.
- Cap the backhead and chuck end.
- Store the hammer horizontally in a dry environment.
▣
LONG TERM STORAGE
When the CS POWER hammers will be stored for a long period of time the following steps should be taken:
- Blow the hammer clear of all water.
- It at all possible, the backhead and chuck should be broken loose on the drill rig, this is much easier than trying to do
so in the shop.
- Disassemble the hammer.
- Inspect and wipe all the parts clean.
- Lubricate all the internal parts with rock drill oil.
- Cap the backhead and chuck ends.
- Store the hammer horizontally in the dry environment.
