GENERAL SAFETY INSTRUCTIONS
Do not stand on seat.
Chair must be on level surface to ensure proper
stability.
Only use chair when fully assembled.
Never use chair if it does not perform according to
this sheet or warranty may be void.
Immediately report any problems to Safco and
always give the manufacturer's date code
information from the label under the seat.
ADJUST THE
HEIGHT RANGE:
The front lever under the seat on the left side
pneumatically adjusts the height of the seat over
a range of about 8". The proper height should
be determined by a combination of variables:
the height of the work surface, the task to be
performed and your body size. Typically, the
chair should be high enough so your arms form
a 90
o
angle at the elbow or slightly greater.
This allows for better circulation in the shoulders
and neck area and also reduces the amount of
fatigue in the forearms and hands. The feet
should lie flat on the ground or footring. To help
insure good posture, maintain a 90
o
angle at the
bend of the knees.
ADJUST THE
SEAT ANGLE:
The seat angle adjustment
lever is the one on the right
side, under the seat. The
seat tilt is important for work
tasks that require leaning
foward. The 10
o
tilt allows you
to lean foward without extra
pressure under the thighs.
Lift the lever and shift your
weight forward until you find
a comfortable position, then
release the lever to lock into
place.
ADJUST THE
BACK ANGLE:
The back angle adjustment
lever is the rear one on the
left side, under the seat. The
22
o
angle adjustment of the
backrest is especially critical
for work tasks that require
leaning forward. Pull up on
the lever and allow the
surface of the backrest to
support the upper body
weight by positioning it to
the natural curve of the spine.
Press down on the lever to
lock into place. The backrest
hinge should tilt freely, to help
prevent twisting of the spine.
ADJUST THE
BACK HEIGHT:
The backrest height
adjustment lever is behind
and below the seat. By sliding
the backrest assembly up or
down, you adjust the height
of the back, which has a
lumbar support curve to it.
Sit centered on the seat. The
curve in the backrest should
fit into the small of your back.
This will reduce the pressure
on the spinal discs, especially
in the lumbar area.
MAINTENANCE
The pneumatic lift in the Cylinder is permanently
lubricated at the factory and needs no further
lubrication.
NEVER LUBRICATE THE
PNEUMATIC LIFT
. Do not remove clip from
bottom of Cylinder. Contact Safco immediately if
clip is missing or damaged. Clean polyurethane
seat and back with soap and water. To repair
small cuts in polyurethane, apply a few drops of
quick drying glue into the cut and press the sides
together until the glue sets.
