cut , increase power in a smooth fashion. If you need more power, press more with your foot. As the cut tapers to the
end, reduce the foot pressure gradually as your hand tilts the graver up and out. With a little practice , this hand/foot
coordination will become as natural as driving a car.
5.3 BIAS 旋钮的使用 HOW TO UESE THE BIAS CONTROL
可通过逆时针调节 BAIS 旋钮，减少脚踏开关的脚踩角度达到雕刻的效果，同时您需要的一些雕刻工作（如点刻法），可通
过调节 BAIS 旋钮，在不需踩脚踏开关的情况下，就可以达到连续雕刻的效果。
After you tune the handpiece , notice that the handpiece starts working as you press down on the foot throttle. Add
one or two pounds of air pressure control knob. Now, open the bias control by turning it counter-clockwise and
notice that it does not take as much pressure on the foot throttle to activate the handpiece . The bias control allows
you to adjust the foot throttle action so you can predict the moment the handpiece will start, giving you optimum
handpiece control. This is a feature that one would use for fine detail work such as bulino or shading. By opening the
bias control fully, you will find that the handpiece will start to work without pressing on the foot throttle. You may find
this function useful for some operations such as stippling .
6. 设备保养 EQUIPMENT MAINTENANCE
6.1
雕刻手柄的清洁
KEEPING THE HANDPIECE CLEAN
当您使用手柄一段时间后，发现手柄力度不够，可将手柄的螺丝旋开， 取出手柄中的弹簧和小圆条，用软质不掉屑的纸或布将
其清洁，同时也将手柄内径清洁，完成后即可装回。
The impact handpiece must be kept clean for proper operation. If operation becomes sluggish , erratic , or fails,
cleaning is needed.Remove the piston and spring from the handpiece . Take each , one at a time, and place in a sheet
of wrting or copier paper. Do not use a paper towel , tissue, or newsprint. Holding it between your fingers buff and
polish of any dirt or residue. Folding the paper, use the edge to clean between the piston grooves and the space
between the spring. To clean the handpiece inside , take the writing or copier paper and twist it to a point. Insert the
paper point into the handpiece and rotate paper and handpiece against each other. This will buff and polish the inside
and clean. IMPORTANT NOTE: DO NOT LUBRICATE PISTON, SPRING, OR BORE.
6.2
脚踏开关的保养
FOOT THROTTLE
在使用脚踏开关工作时，应尽可能的保证地板的干净，以免杂质进入脚踏开关，造成其损伤。当停止工作后，请将脚踏开关放
在工作台或工作椅上。
The throttle should require little maintenance, It should be cleaned periodically. OILING: Periodically, place a drop of
oil on the throttle hinges. Keep the floor clean. When you sweep or vacuum, place foot throttle on your bench or chair.
6.3
气源配件的保养
AIR SYSTEM
在您使用雕刻机一段时间后，您应该气源过滤器 16（pic.3 图）里的水清洁赶紧，只需将气源过滤器底部的针头往上按住即可。
也应将雕刻机底部的一个内六角机米螺丝旋开，让水排干净后，再锁上螺丝即可。
If large amounts of water and contaminants are in the air supply to the unit , more frequent attention must be given
to the unit filter. The bowl must be drained frequently to prevent water from entering the rotary valve,hoses,handpiece,
etc. In addtion, the filter element must be cleaned and/or replaced frequently. If moisture is noted in the handpiece or
throttle hoses, shut the unit down immediately and drain the filter bowl.
Then proceed as follows:
6.3.1 Disassemble and clean impact handpiece(s) and reassemble.
6.3.2 Reduce pressure setting to 10 psi and turn unit ON to purge mositure form valves,hoses,etc.
6.3.3 Located on the lower back of the machine is the drain plug to the internal air reservoir. Using a hex wrench,
remove the plug and drain any mositure from reservoir. Replace drain plug.Bfore using machine again,figure out
where the mositure came from and fix the problem. It may require an addtional filter(s) or water trap in the line.
