Assembly of the Handle and Throttle Mechanism
1. Install the Air Strainer Body (6) in the Handle.
2. Install Throttle Valve Plunger (9), Throttle Valve (4),
Throttle Valve Spring (8) and Throttle Valve Cap (7).
3. Align Throttle Lever (2) in Handle and drive in
Throttle Lever Pin (3).
4. Reposition the tool in a vise with leather–covered or
copper–covered jaws by clamping the Handle across
the Throttle Lever Pins with the Barrel up.
5. Slide Locking Ring (16) over splines on Barrel,
aligning castellations on Locking Ring with
castellations in Handle. Tap Lock Ring lightly in
several places to secure in position.
6. Using the No. 34SR–54 Exhaust Deflector Pliers,
spread apart and install the Exhaust Deflector (17).
7. Install new Nozzle (14) after Tool has been
assembled. Using a soft hammer, start new Nozzle,
externally beveled end first, squarely into Barrel bore.
For Hexagon Nozzles, be sure to position the Nozzle
so that the flats are in the desired position relative to
the Handle. Support the Handle directly beneath the
Barrel and press in the new Nozzle until it seats.
8. Install Retainer (33) on front of Barrel and secure
with Lock Spring (33A) or Flat Spring and Pin (33B).

TROUBLESHOOTING GUIDE

Probable Cause
Dirt or oil gum accumulationon
internal parts
Worn Valve
Worn Piston and/or accessory.
SAVE THESE INSTRUCTIONS. DO NOT DESTROY.
Installation of Oversize Piston
Greater wear occurs near the center of the Barrel bore than
at either end. To obtain full benefit from an oversize
Piston (15), it is necessary to lap the Barrel (13) until the
bore is of uniform size for its entire length.
Select and install the proper size Piston after truing up the
Barrel bore. Pistons are furnished .004" or .008" oversize.
Installation of Oversize Nozzle
The Nozzle (14) must be a tight press fit in the front of the
Barrel (13). After the Nozzle has been replaced a few
times, the Barrel may become enlarged to the extent that
the Nozzle is no longer tight. If this condition is noted, an
oversize Nozzle should be used. Several oversize Nozzles
are available (see part list section) so that the size of the
Nozzle can be increased from time to time as necessary.
Each oversize Nozzle is plainly etched with the amount of
oversize; a standard Nozzle is unmarked. Examine a
Nozzle that can be pressed easily from the Barrel. If it is
unmarked, use the first oversize; if it is marked .0025",
use one .0035", etc. when reassembling the Scaler. See
MAINTENANCE TOOLS on Page 6 for Nozzle removal
tool.
Pour about 3 cc of a clean, suitable, cleaning solu-
tion into the air inlet and operate for 30 seconds.
After flushing, pour about 3 cc of oil into the air
inlet and operate the tool for 5 seconds to coat the
internal parts with oil.
Replace the Valve.
Replace Piston and or accessory.
