Assembly
Refer to the Illustration(s) and Parts List for correct
orientation and placement of parts.
Replace any O-rings, V-rings, seals, and gaskets on
parts that have been disassembled. Apply hydraulic
uid or O-ring lubricant to all O-rings and all metal
surfaces which they must slide over. When installing
an O-ring which must slide over sharp surfaces, use a
rolling motion and be careful not to damage the O-ring.
Wherever the assembly results in metal-to-metal
contact, coat the surfaces with hydraulic uid or O-ring
lubricant.
Motor Assembly
1. If bearings (53 and 56) have been removed from the
motor cap (55) and saw head (52), replace them.
Install O-ring (54) in saw head.
2. Install ball bearing (64) over threaded end of drive
shaft (57). Install non-threaded end of drive shaft
(57) through front of cavity in saw head assembly
(52). Secure with retaining ring (65). Install drive
pin (60) into idler shaft (58) and install idler shaft
into cavity on rear side of saw head assembly (52).
Install Woodruff key (59) into drive shaft (57).
3. Install one gear (61) onto idler shaft (58), aligning
notch in gear over drive pin (60). Install one gear
(61) on drive shaft (57), aligning notch in gear over
Woodruff key (59).
4. Install gasket (62) on saw head assembly (52). Install
dowel pins (63) in saw head assembly.
Install motor cap (55) on saw head assembly,
using the line scribed during disassembly to align
parts correctly. Secure motor cap (55) to saw head
assembly with washers (70) and socket head cap
screws (66). Torque to 9 newton-meters (80 in-lb).
5. If metering screw has been removed, install O-ring
(67) on metering screw (68). Install metering screw,
bottoming it out in the cavity, and backing it off
about 1/2 turn.
Note: Metering screw is not adjusted at this point.
After assembly is completed, adjust automatic oiler
before using the tool.
6. If O-rings (69) have been removed, install a new
O-ring inside each port of saw head assembly (52).
Saw Bar and Chain
1. Install sprocket key (17), sprocket washer (16),
sprocket (18), sprocket adapter (26), and stop nut
(19) on threaded end of drive shaft. Ensure that
sprocket adapter is assembled onto shaft with
1.500 dia. face oriented toward stop nut.
2. Set saw head down at. Install dog (21) with small
diameter side facing out. Install adjusting screw (20)
into back side of saw head and thread into dog.
3. Place bar with chain wrapped around it onto saw
head. Ensure dog is placed in the guide hole around
the outer edge of the bar. Place cover (14) with hex
head cap screws (15) over bar and secure screws
into saw head loosely but enough to hold bar at
onto saw head with dog in guide hole.
4. Place chain around sprocket and bar.
Note: Lubricate the saw chain (13) well (especially a
new chain) before installation. Oil all joints and work
oil into rivet holes. The best way to oil a new chain is
to soak it in oil before installation.
5. Tighten adjusting screw (20) until proper tension is
achieved. (Refer to “Adjusting Chain Tension” in the
“Maintenance” section of the Instruction Manual.)
6. Secure hex head cap screws (15) to 16.9 newton-
meters (150 in-lb).

Handle Assembly
(Serial Codes AMM, AMN, AMP, FRM, FRP, and FRR)
1. Install O-rings (47) in the valve handle (27).
2. Install O-ring (48) in valve handle (27). Install
O-rings (34 and 48) in sleeve (28). Install sleeve (28)
in valve handle (27). Secure with external retaining
ring (49).

Inner and Outer Tubes
1. Hold the two inner tubes (2 and 3) together, and
slide one O-ring (22) over the tubes, halfway down
the length of the tubes. Turn one of the tubes end
for end, so that the O-ring forms a gure 8 around
the tubes. Slide one O-ring (22) in a gure 8 over
each end of the tubes, pushing the O-ring down
approximately 15.9 cm (6-1/4") from the end of the
inner tubes.
Note: Inner tube (2) is the pressure tube, and should
be marked either with marking tape or with dye on
both ends. Be careful to install the marked tube in
P port of both the motor assembly and the valve
assembly. Improper installation of the inner tubes
will cause the saw to run backwards.
2. Lubricate tips of inner tubes with hydraulic oil to
ease assembly. Press inner tube (3) into the top
(return) port of motor assembly (1). Press inner tube
(2) into the lower (pressure) port of motor assembly,
which is marked P.
3. Press one nut carrier (7) into corresponding holes
in end of outer tube (4). Nut carrier may be glued to
outer tube to hold it in place during assembly. Slide
the outer tube over the inner tubes, with the end
of the outer tube which has small holes for secur-
ing to the handle assembly (8) away from the motor
assembly (1). Place the outer tube into the motor
assembly, aligning the nut carrier under the holes
in the motor assembly. Apply one drop of thread-
locking compound (Loctite 242 or equivalent) to
three oval head machine screws (9). Install screws,
securing outer tube to motor assembly.
4. For proper tool operation, the same inner tube (2)
that was installed in the pressure port of the motor
assembly (1) must be installed in the pressure port
of the handle assembly (8). Lubricate tips of inner
tubes with hydraulic oil to ease assembly. Press
inner tube (3) into the top (return) port of handle
assembly (8). Press inner tube (2) into the lower
(pressure) port, which is marked P.
5. Insert plug (5) and O-ring (6) in outer tube (4) and
install in valve handle (8). Secure with cap screw
(10) and washer (11).
