Safety
Checks
-
Continued
prolonged use may lead to gradual loss of hearing. Wear
suitable ear protection and operate the tool with a muffler.
-
Wear
safety goggles to protect eyes against flying particles.
-
Keep
hoses in good condition. Check hoses
for signs
of wear
and ensure that fittings are secure. Accidental
disconnection while hose is pressurized can make the hose
whip and can be a safety hazard.
-
To
avoid Injury from ejected steel, Replace worn or broken
parts to maintain proper steel retention. Ensure that chisel
is secured. Check latch mechanism fur correct locking.
-
Do
not operate tool with chisel without first engaging chisel
against the' job.
-
Safety
shoes are recommended to protect feet during operation.
AIR
REQUIREMENTS
All
Edicon demolition tools require air at a steady 80-90 PSIG
(5.6-6.3 bar) pressure. The air should be clean (filtered) and
dry (moisture free).
The
pipes and/or hoses leading to the tool should be of the minimum
recommended diameter. For the EM83A/EM-83AS breaker the size is
3/1111 Internal diameter.
We
recommend an air line separator to remove moisture which Is
usually present in air lines.' Also it is Important 'to have a
filter to remove any particles. These air line accessories
should be as close to the tools as operation will permit.
The
EM83A/EM-83AS breaker consumes 88 CFM of air in continuous
operation. Normal use is intermittent, so the average
consumption will be lower than 88 CFM, the extent depending upon
the type of usage. However always make sure that there is more
than 88 CFM available on the air line by checking output of
compressor and number of connected, operating, tools.
LUBRICATION
REQUIREMENT:
A)
QUANTITY
Always
ensure that a Line-Lubricator is Installed on the air-supply Line as
,close
as possible to the tool, and that the discharge rate is
adequate. It is also recommended to top up the in built oil chamber on the
handle of the tool as and when required (every shift)
One
practical way to test if the tool is receiving enough oil is the
presence of oil mist in the tool exhaust. The presence of this
mist can be checked by holding a surface (ones hand) in the
exhaust during operation, if the surface appears oily than the
lubrication rate is adequate.
Another
simple test is to see if the shanks of chisels being used appear
oily and if they are, it indicates adequate lubrication.
B)
QUALITY OF LUBRICATION:
Recommended
Oil for EM83A/ EM83AS Breakers is any of the following.
|
1)
SPINTEK-22
2)
BHARAT HYDROL-22
3)
SERVOSPNY 22
4)
CASTROL HYSPIN AWS-22 or equivalent.

DO’S
AND DON’TS
1)
Daily blowout hoses and ensure hoses are in good condition and
clean.
2
)Pour in an ounce of oil into the air inlet before connecting
hoses.
3)
Do not operate tool without the chisel being in contact with the
work.
4
)Ensure chisels are in top condition, i.e_ well sharpened.
5)
Retighten bolts on the breaker to recommended torques
frequently.
6)
When not in use, plug openings to avoid ingress of dirt.
7)
Observe safety precautions.
8)
Never operate at pressure over 90 PSIG (6.3 bar).
MAINTENANCE:
If
the tool is being used extensively, it is strongly recommended
to fix up a regular preventive maintenance programme. The tools
are very simple to dissemble/resemble and we recommend that the
tools is dismantled completely and parts checked for wear or
damage and replaced accordingly .
HOW
DO DISASSEMBLE AND RE-ASSEMBLE EM-83A/EM-83AS
Disassemble
breaker by opening up the front head and back head bolts
taking
care to see that the components are not damaged by scoring and
careless
handling.
Check
the following
A)
Check for scoring or damage to internal components.
B)
Check valve parts and valve action.
C)
Check anvil block, if there is distortion at the ends, replace.
D)
Check retainer action.
Thoroughly
clean oil parts, replace worn/damaged parts and re-assemble as
follows:
1)
Before assembly, coat all parts with recommended Oil .
2)
Pull up back head bolts (22) evenly by alternating from 'one to
the other to distribute the
load and to minimize bolt failure. Torque 125-150 ft.lbs.
3)
Draw up front head bolts (21) alternatively, a little at a
time,compressing springs (29) evenly. When springs bottom, loose
.bolts ½ to 1 turn.
Assemble
length 2 3/8" - 2 5/'16".
4)
Install air inlet swivel (8) and tighten nut (11) to 125-150
ft.lbs. torque. Be sure "0" Rings (9 & 10) are in
position.
5)
When assembly is complete, fill oil chamber and tighten oil plug
(32) to 80-100 ft.lbs. torque. Pour about 1/2 Oz. Recommended Oil
into air inlet swivel (8) and operate tool ON REDUCE THROTTLE FOR
10-15 seconds.
