PREPARATION
LOADING MAGAZINE
NOTE: Always use Josef Kihlberg original staples.
The correct designation is marked on each
stapling head.
1. Pull the pusher (1) back and lift up the magazine
breech (2). (See Figure 1)
2. Insert staple strips (3) from the rear. (See Figure 1)
WARNING! Do not overload the magazine, as
this may damage the pusher when the breech
is closed.
Never release the pusher directly from the rear
when the magazine is empty; carefully guide it
forward by hand.
ADJUSTING ANVIL
Though the tool is tested carefully before delivery, it may
have seen rough treatment during transport and the
anvil may therefore have to be adjusted.
1. Slide down a staple (4) by hand until the staple legs
are visible. (See Figure 2)
2. Move the staple towards the anvil (5) until the
staple legs hit the anvil symmetrically. (See Figure 2)
3. If necessary, loosen the screw (6) and center the
anvil to the staple. Lock screw after adjusting.
(See Figure 2)
4. Make a test-stapling in a piece of carton. When
everything is in order, you can start using the tool.

SAFETY
• Never use oxygen, combustible gases, CO2, steam
or high pressure gas tanks as power sources for the
this tool. The tool could explode and cause serious
injury.
• Use only dry, clean, pressure-regulated compressed
air to drive the tool.
• Connect the tool to the compressed air system
before the fastener unit is loaded.
• The maximum permitted air pressure for the tool is
116 p s i .
• The maximum supply pressure is 127 psi.
• Avoid excessive pressure drop by ensuring that the
minimum internal diameter of the air hose is 3/8"
and that of the nipple is a minimum of 6/32".
• The stapler and its hose are equipped with a
connection nipple that automatically exhausts air
from the tool after it has been disconnected.
• Adjust the air pressure to the lowest level that will
bend the staples correctly. Start at approximately
5.0 bar and raise this by 0.5 bar increments until the
correct pressure is found. Never exceed 8 bar.
• Low air pressure will result in low maintenance costs.
• When working with small cartons, there is a risk of
injury to fingers holding the item.
• Never hold your hand under or close to the stapling
head.
• Keep hands clear of arms carrying the stapling
head when operating the foot valve.
