AIR SUPPLY
For ecient performance, a regulated supply of clean, dry air is required (90 p.s.i. at the tool). Most air tools will
give superior service if the air is moisture free and lubricated, plus down time will be minimized. If the compressor
is pumping excessive water, a cooler or moisture separator (TX-MSS-400 or TX-MSS-800) should be attached to
the compressor or air line. A lter, pressure regulator and Texas Pneumatic in-line lubricator (TX-0L) should be
part of the air line system to the tool. e air supply line should be a minimum 3/8” I.D. hose with no restrictive
couplings or ttings in the hose line. If quick disconnect air couplings are used, they should denitely be sepa-
rated from the tool by the use of a hose whip (TX-1HW).
LUBRICATION
An in-line lubricator such as the Texas Pneumatic TX-0L is recommended. If an automatic lubricator is not used,
it is recommended before using and aer 2-3 hours use to pour several drops of oil into the air inlet port. Texas
Pneumatic lubricating oil (TX-PL001) or 5 wt. oil of good grade is recommended. A heavy oil will cause loss
of power and eciency. In the matter of preventative maintenance, Texas Pneumatic tool ush (TX-TF001) or
similar solvent can be used to ush the tool. Add a couple of teaspoons to the air inlet port and operate the tool
for a few seconds. It may be necessary to do this several times. e above should be done anytime the scaler be-
comes sluggish or erratic or stops working. Flushing of the tool will most likely remove any foreign particles. Aer
ushing and always before storage (this is most important if the air line has excessive moisture), the tool should be
re-lubricated to prevent rust which will cause the tool to malfunction.
PREPARING FOR OPERATION
e TX1B is convertible and can be used either as a chisel scaler or as a needle scaler depending on the applica-
tion. To remove the chisel, pull up on the retainer (TX-00956). is should allow the chisel to slide out of the
tool. To place chisel in tool, do the reverse but making sure the chisel slot faces the retainer. e same applies
to the needle driver (TX-00045). Always operate the scaler with a chisel or needle driver in the tool and held
rmly against the work surface. Damage to the tool nose (TX-00963), cylinder sleeve (TX-00700) and retainer
buer (TX-00527) may occur if the tool is not held against the work surface. e backhead should be checked
occasionally to make sure it is tight. On lever throttle scalers, Loctite is used on the throttle valve cap (TX-00207)
when assembled at the factory. is should not be in need of attention until the cap is removed for inspection
or repair. e use of Loctite is strongly recommended when replacing the cap to prevent it from vibrating loose.
e “O” ring (TX-00302) on the throttle valve (TX-00782) should be replaced whenever the tool is inspected,
plus the throttle valve spring (TX-00078) and the utter valve (TX-00196) if they appear worn. It is suggested
that high wear parts such as retainers (TX-00956), retainer buers (TX-00527) and retainer clips (TX-00554)
be kept on hand as back-ups. To disassemble the tool, remove the retainer clip (TX-00554), retainer (TX-00956)
and retainer buer (TX-00527). Place the ats on the end of the barrel in a brass jawed vice and then unscrew
backhead lock ring (TX-00882) until it is loose; then unscrew backhead (TX-00781) and remove. Valve parts
(TX-00173, TX-00508, TX-00196) and plunger (TX-00373) will fall out when tool is turned upside down. To
remove tool nose (TX-00963) and cylinder sleeve (TX-00700), it is necessary to press them from the front part
of the barrel out through the rear of the barrel. Re-assembly is in reverse order. Use TX1B-TK tool kit to aid with
disassembly and re-assembly
Last, but most importantly, approved safety glasses should be worn at all times when operating this or any
other percussion tool.
