TRIMMER SAFETY WARNINGS 
1. 
Hold power tool by insulated gripping surfaces, 
because the cutter may contact its own cord. 
 
Cutting a "live" wire may make exposed metal parts 
of the power tool "live" and shock the operator. 
2. Use clamps or another practical way to secure 
and support the workpiece to a stable 
platform.Holding the work by your hand or against 
the body leaves it unstable and may lead to loss of 
control. 
3. Wear hearing protection during extended 
period of operation. 
4. Handle the bits very carefully. 
5. Check the bit carefully for cracks or damage 
before operation. Replace cracked or 
damaged bit immediately. 
6. Avoid cutting nails. Inspect for and remove all 
nails from the workpiece before operation. 
7. Hold the tool firmly. 
8. Keep hands away from rotating parts. 
9. Make sure the bit is not contacting the 
workpiece before the switch is turned on. 
10. Before using the tool on an actual workpiece, 
let it run for a while. Watch for vibration or 
wobbling that could indicate improperly 
installed bit. 
11. Be careful of the bit rotating direction and the 
feed direction. 
12. Do not leave the tool running. Operate the tool 
only when hand-held. 
13. Always switch off and wait for the bit to come 
to a complete stop before removing the tool 
from workpiece. 
14. Do not touch the bit immediately after 
operation; it may be extremely hot and could 
burn your skin. 
15. Do not smear the tool base carelessly with 
thinner, gasoline, oil or the like. They may 
cause cracks in the tool base. 
16. Use bits of the correct shank diameter suitable 
for the speed of the tool. 
17. Some material contains chemicals which may 
be toxic. Take caution to prevent dust 
inhalation and skin contact. Follow material 
supplier safety data. 
18. Always use the correct dust mask/respirator 
for the material and application you are 
working with.

WARNING: 
DO NOT let comfort or familiarity with product (gained 
from repeated use) replace strict adherence to safety 
rules for the subject product. MISUSE or failure to 
follow the safety rules stated in this instruction 
manual may cause serious personal injury. 
FUNCTIONAL DESCRIPTION 
 
CAUTION: 
• Always be sure that the tool is switched off and 
unplugged before adjusting or checking function on 
the tool. 
Adjusting bit protrusion 
Fig.1 
To adjust the bit protrusion, loosen the locking lever and 
move the tool base up or down as desired by turning the 
adjusting screw. After adjusting, tighten the locking lever 
firmly to secure the tool base. 
 
NOTE: 
• When the tool is not secured even if the locking 
lever is tightened, tighten the hex nut and then 
tighten the locking lever. 
Switch action 
Fig.2 
CAUTION: 
• Before plugging in the tool, always check to see 
that the tool is switched off. 
To start the tool, press the "ON ( I )" side of the switch. To 
stop the tool, press the "OFF (O)" side of the switch. 
Electronic function 
The tool equipped with electronic function are easy to 
operate because of the following features. 
Constant speed control 
Electronic speed control for obtaining constant speed. 
Possible to get fine finish, because the rotating speed is 
kept constant even under load condition. 
Soft start 
Soft-start feature minimizes start-up shock, and makes 
the tool start smoothly. 
Speed adjusting dial 
Fig.3 
The tool speed can be changed by turning the speed 
adjusting dial to a given number setting from 1 to 6. 
Higher speed is obtained when the dial is turned in the 
direction of number 6. And lower speed is obtained when 
it is turned in the direction of number 1. 
This allows the ideal speed to be selected for optimum 
material processing, i.e. the speed can be correctly 
adjusted to suit the material and bit diameter. 
Refer to the table for the relationship between the 
number settings on the dial and the approximate tool 
speed.
