Using the Tripod
A tripod can be purchased from your
nearest measurement tool dealer. The
below instructions are generic only and
set-up methods may vary between models.
Refer to the documentation from the tripod
manufacturer for details.
• Extend the tripod legs to the required height
and ensure the legs are spread wide enough
so that the tripod platform is stable. Secure the
legs in place (refer to the documentation from
the tripod manufacturer for details).
• Place the laser level onto the tripod and mount
via the male thread (5/8” or 1/4”) into the base
until firm. Do not over tighten as this may
cause damage to the laser level or tripod.
NOTE: adjustment methods will vary on tripod
models. Always ensure that any locking levers are
unlocked before making adjustments and returned
to the locked position when the adjustment is
complete.
If using an elevating tripod with a measuring scale
on the centre column, the height can be adjusted
as required.
WARNING! Attaching the laser to a
tripod without the correct thread size
may cause damage.

Trouble Shooting
ERROR CAUSE & SOLUTION
If the above troubleshooting steps do not resolve any issue that you may have, please contact 24-hour support.
Laser level does
not power on
• Check that the battery is charged.
• Check the battery compartment for signs of damage and
ensure that the compartment and battery terminals are clean.
Laser level does
not remain on
for long periods of use
• Check that the battery is charged.
• Check the battery compartment for signs of damage and
ensure that the compartment and battery terminals are clean.
Laser level does not
level in the unlocked
self-levelling mode
• The laser level may be outside of its self-levelling range and
may require an adjustment before self-levelling can commence.
• The laser level may have impact damage and may require
repairs to become operational.
I am seeing multiple
lines on the same
wall / surface area in
parallel to one another
• Check that no highly reflective surfaces are on the opposite side
of the laser level (e.g., glass). Reposition the laser level to another
area or block the laser beam from reflecting off the reflective surface.
• If the lines are not in parallel you are seeing a diffraction line
from the laser level. This is common due the design optics of
3D laser levels.
