Working Advice - Bosch GCL 2-55 Operating/Safety Instructions Manual

– The difference d of both marked points I and III on the ceiling results
in the actual deviation of the measuring tool to the plumb line.
The maximum permitted deviation dmax can be calculated as follows:
dmax = double the distance between floor and ceiling x 0.027 in (0.7
mm/m)
Example: If the distance from the floor to the ceiling is 16 ft (5 m), the
maximum deviation is dmax = 2 x 16 ft x 0.0275 in = 0.275 in (2 x 5
m x 0.7 mm/m = 7 mm/m). The marks must therefore be maximum
0.275 in (7 mm) apart.

Working Advice

• For marking, always use only the center of the laser point or the
laser line. The size of the laser point as well as the width of the laser
line change with distance.
Working with the Tripod (Accessory)
A tripod offers a stable, height-adjustable measuring support. Position
the measuring tool with the 1/4" tripod mount 8 onto the thread of the
tripod or a commercially available camera tripod. Tighten the measur-
ing tool with the tripod mounting stud.
– Adjust the tripod before switching on the measuring tool.
Fastening with the Positioning Device (Accessory)
(see figure H)
With the positioning device 17, you can fasten the measuring tool,
e.g., to vertical surfaces, pipes or magnetisable materials. The univer-
sal holder is also suitable for use as a ground tripod and makes the
height adjustment of the measuring tool easier.
– Adjust the positioning device 17 before switching on the measuring
tool.
