Assembly

Refer to the Illustrations 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
fluid 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 fluid 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 flat. 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 flat
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 this manual.)
6. Secure hex head cap screws (15) to 16.9 newton‑
meters (150 in‑lb).
