When assembling the lap siding attachment to the sawmill, do not
torque the bolts to hardware Class/Grade specifications. Snug the
hardware, then tighten a further ¼—½turn. Tightening bolts to torque
spec can crush metal tubing, ruining the components.
BOLT TORQUE WARNING!

2. SETUP BLOCKS
Before starting the partial disassembly of the right-side carriage leg, setup blocks must be
installed on the track in order to support the weight of the carriage while components are
removed in later steps.
For the HM126, HM130, or HM130MAX; roll the sawmill carriage until the rear carriage wheel is
just behind the pair of track holes and the front carriage wheel is past the quad set of track
holes.
**Note: on ground-mounted sawmills, the lap siding attachment requires a minimum of
2.5 in [63.5 mm] of vertical track clearance, measured from the bottom of the track rail to
the levelling foot/base.**

For HM122 sawmills, roll the carriage until the front carriage post is centred on of the track rail
seams. The setup blocks for the HM122 will be installed on the outer two holes of the 4 hole

Assemble the two (2) setup blocks to the outer face of the track rail using two (2) M10 X 25 mm
hex bolts through the holes shown below.
With the setup blocks in place, the inner carriage plate will support the weight of the sawmill
carriage once the carriage wheels are removed. Note: the setup blocks sit approximately ⅛in
[3 mm] lower than the inner carriage plate prior to wheel removal—this is normal.
