Ensure the battery is fully charged before transporting the sawmill.
If the battery is not fully charged, excessive vibration could reduce
the overall service life of the battery.
Sawmill Setup Safety
Do not set up the mill on ground with more than
a 10 degree incline. Setting up the mill on an
incline could cause it to tip over.
If setup on an incline is necessary, put blocks
under one side of the mill or dig out areas for
the legs to keep mill level.
Use a lifting device (fork lift, crane, etc.) for parts
over 100 lbs.
Use two persons for lifting parts over 50lbs.1

https://www.cdc.gov/niosh/docs/94-110/
EMERGENCY TREATMENT FOR CONTACT WITH BATTERY COMPONENTS (LEAD/SUL-
FURIC ACID) per SDS (Safety Data Sheet):
EYE CONTACT Sulfuric Acid and Lead: Flush eyes immediately with large amounts
of water for at least 15 minutes while lifting lids. Seek immediate med-
ical attention if eyes have been exposed directly to acid.
SKIN CONTACT Sulfuric Acid: Flush affected area(s) with large amounts of water
using deluge emergency shower, if available, shower for at least 15
minutes. Remove contaminated clothing, including shoes. If symp-
toms persist, seek medical attention. Wash contaminated clothing
before reuse. Discard contaminated shoes.
Lead: Wash immediately with soap and water.

vomiting or aspiration into the lungs may occur and can cause perma-
nent injury or death; consult physician.

SECTION 3 SETUP
3.1 Assemble the bed sections
The tools needed are:
Socket, 17mm
Ratchet handle
Ratchet extension bar (optional)
Combination wrench, 17mm
Assemble the bed on firm, level ground. Failure to do so may
cause the sawhead to tip, causing serious injury or death.
1. Assemble all of the bed sections using track rails and cross rails, and one cross member
where each bed section joins together.(See FIG. 3-1 .)
a. Attach two cross rails per bed section. Make sure to place the cross rails closer
together, leaving room for the sawhead assembly, as shown.
b. Attach the track rails to the cross rail. Make sure all of the cross rails face the
same direction. (See FIG. 3-2 .)
NOTE: Do not attach the catch rails at this time!

2. Assemble the remaining track rails and cross rail in a similar fashion. (See FIG. 3-2 .)
3. Connect the bed sections using a connecting plate, a clamp, and hardware.
a. Attach the connecting plate (X100-934) to each bed section, joining them together.
b. Tighten the side of the plate that has the fixed holes. Do not fully tighten the bolts
(M10-1.5x30) on the side of the plate that has slotted holes.
c. Set the clamp in place by inserting the larger notch first (on bottom) and then tilting
the clamp in and upward to catch the smaller notch (on top). (See FIG. 3-3 .)
d. Tighten the bolts on the clamp (M10-1.5x85) to draw bed sections together.

NOTE: Be sure the slotted holes on the connecting plate are con-
nected to the same bed section on both sides of the bed frame.
f. Repeat for the remaining 3 connections.
g. Attach the cross member between the bed sections.
NOTE: Optional bed extension sections may be added at this time, in
the same manner as the standard bed sections.
