Troubleshooting - U-Line H-3070 Manual

CHANGING THE STAPLING HEAD
1. Loosen the screws (30, 31). (See Figure 9)
NOTE: In order to loosen the rear screw (31)
the stapling head must be lifted 90°.
2. Mount a new head and make a course lateral
adjustment.
3. Tighten the screws and reassemble.
• Never use oxygen, combustible gases, CO2, steam
or high pressure gas tanks as power sources for
the 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 psi.
• 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".

TROUBLESHOOTING

• Check that the right type of staples are being used.
• Check that the feeder spring is OK.
• Check that the staple pusher is OK.
• Check that the staple track is clean with no dirt inside.
• Check that the return spring in the stapling head is OK.
• Check that the stapling head trip springs are OK on head.
• Check that the side plates are OK on head.
30
• 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.
