Service and Operations
AIR SUPPLY
For ecient performance, a regulated supply of clean, dry air is required (90 psi 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 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 separated 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 recom-
mended. 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 becomes 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 TX456 is convertible and can be used either as a chisel or as a needle scaler depending on the application. To remove the chisel,
rotate the chisel lock ring (P-088813) counter clockwise and pull out the chisel. To place the chisel in the tool, do the reverse. Make sure
the slot in the chisel lines up with the steel ball (P-070416) in the chisel sleeve (P-050933). e same applies to the anvil (P-100144) or
needle driver. Always operate the scaler with a chisel or needle driver in the tool and held rmly against the work surface. Damage to the
cylinder or barrel (P-456BRL) and cylinder sleeve (P-041557) may occur if the tool is not held against the work surface. e backhead
(P-109273) should be checked occasionally to make sure it is tight. On lever throttle scalers, Loctite is used on the throttle valve plug
(P-009876) when assembled at the factory. is should not be in need of attention until the plug is removed for inspection or repair.
e use of Loctite is strongly recommended when replacing the plug to prevent it from vibrating loose. e “O” ring (TX-00302) on
the throttle valve (P-091582) should be replaced whenever the tool is inspected. Also, check the throttle valve spring (P-091585) and
the metallic cycling valve (P-043310) to see if they appear worn. It is also possible to use a polymer cycling valve (P-119294). ese
valves are interchangeable.
To disassemble the tool, remove chisel or needle driver as previously described. Clamp the chisel into a vise and slide the scaler over it.
Unscrew the cylinder lock nut (P-109271) until it is loose; then unscrew backhead (P-109273) and remove. Spacer (P-125736), valve
parts (P-043309, P043310 or P-119294 and P-084034) and the piston (P-084033) will fall out when the tool is turned upside down.
Metallic shims (P-084037 (.005) or TX-00947 (.010) may have also been used. ese are for alignment purposes and allow the lever
to correctly align with the barrel. To remove the cylinder sleeve (P-041557), it is necessary to press it from the front of the barrel out
through the rear of the barrel. To remove the chisel sleeve (P-050933), press it from the rear of the barrel out through the front. Re-
assembly is in reverse order.
***VERY IMPORTANT***
When installing the chisel sleeve in the tool, make sure alignment marks line up. (See Picture 1 on back) When installing the cylinder sleeve,
position the slot on the bottom of the liner (See Picture 2) with the exhaust holes in the bottom of the barrel. (See Picture 3)
Approved safety glasses must be worn at all times when operating this or any other percussion tool. A maximum 90 psi compressed air pressure
is recommended for operating this tool. “WF” Notched Shank - 1/2” Quarter Octagon
