Air Regulator
Regulated air pressure is necessary for proper
performance of the air hammer. The Snap-on AHR426
Regulator, or equivalent, will adjust and maintain the
recommended air pressure of 90 psig (6.2 bar, 620 kPa).
Pressure less than this reduces efficiency, while pressure
greater than this increases blows and speed beyond the
rated capacity—creating potential hazards and possible
damage to the air hammer. Check the air pressure at the
regulator while using the hammer in a normal manner.
Air Line Lubricator
• Do not use a heavy grade of oil because stalling and low
performance will result.
The preferred method of lubricating the air hammer
motor is to use an air line lubricator such as the Snap-on
AHR428 Lubricator. It should be filled with Snap-on IM6
Air Motor Oil or a good grade of SAE 10W oil. If an air line
lubricator is not used, lubricate the air motor by injecting
approximately 1/8 oz. (3.7 ml) of IM6 Air Motor Oil into
the air inlet of the hammer each day before using it. IM6
Oil is specially formulated for air tools and no flushing
solvent is needed.
Flushing
If the unit seems sluggish apply 3 or 4 squirts of IM6 Air
Motor Oil into the air inlet of the hammer each day before
using, and again at the end of each work day.
Air Strainer
The regulator inlet bushing houses a copper-mesh air
strainer. Clean this strainer occasionally, especially when
the tool does not get an ample supply of air. Remove the
air filter screen using a Snap-on pick, part number
3ASH90A, or a similar tool. If the strainer is damaged or
permanently plugged, replace it with Snap-on part
number PGS1-11.
Featherable Trigger
The trigger controls the air flow which regulates the
power and speed of the hammer. The distance of trigger
movement directly controls the air flow to the
air motor.
Power Regulator
Power output is governed by the air line pressure and the
regulator setting. An air line pressure of 90 psig (6.2 bar,
620 kPa) is recommended. The regulator is located at the
bottom of the housing handle and regulates the power
and frequency of the impact blows. It has four settings.
"I" is the lowest power/frequency setting and "IIII" is the
highest.
Figure 2 shows the regulator at the maximum power
"IIII" setting.

Installing Bits
Screw universal retainer chuck completely on threaded
end of air hammer barrel.
Disconnect air supply before changing hammer bits.
When inserting the hammer tool bit (accessory) into the
retainer chuck, follow the procedure described below.
1. Pull back on the outer chuck sleeve (pull toward
threaded end).
2. Place hammer tool bit into retainer. Note: Check that
the collar of hammer bit has cleared the four steel
balls on the inside of retainer.
3. Release outer chuck sleeve and check that hammer
tool bit is securely in retainer.
PH200D Retainer Chuck
PH200D retainer chuck is included on PH3050BR model.
This chuck allows non-turning bits to be used with the air
hammer when jobs demanding increased control and
accuracy are encountered.
