Operation - Black & Decker ST182320 Original Instructions Manual

EngliSh
Fitting the guard (Fig. D, E)
Warning! Remove the battery from the appliance before
attempting to attach the guard, edge guide or handle. Never
operate appliance without guard firmly in place. The guard
must always be on the appliance to protect the user.
♦ Remove the screw from the guard.
♦ Turn the trimmer upside down so that you are looking
down at the spool cap (16).
♦ Turn the guard (8) upside down and slide it fully onto the
motor housing (12). Make sure the tabs (13) on the guard
slip into the holes (14) of the motor housing as shown in
Figure D.
♦ Continue to slide the guard on until you hear it "snap"
into place.
♦ Using a phillips screwdriver, insert the guard screw and
tighten securely as shown in Figure E to complete the
guard assembly.
♦ Once the guard is installed, remove the covering from the
line cut-off blade, located on the edge of the guard.
Warning! Never use the tool unless the guard is properly
fitted.
height adjustment (Fig. F, g–g3)
Warning! Adjust the length of the trimmer to obtain proper
working positions shown in Figures G–G3.
♦ The overall height of the trimmer can be adjusted by
loosening the height-adjust collar (5) and rotating it in the
direction of the arrow shown in Figure F.
♦ Move the upper housing straight up or down. When the
desired height is achieved, tighten the collar by rotating it
opposite of the direction shown in Figure F.
Releasing the cutting line
In transit, the cutting line is taped to the spool housing.
♦ Remove the tape holding the cutting line to the spool
housing.

Operation

Warning! Always use proper eye protection.
Warning! Before you begin trimming, only use the appropriate
type of cutting line.
note: Inspect area to be trimmed and remove any wire, cord,
or string-like objects which could become entangled in the
rotating line or spool. Be particularly careful to avoid any wire
which might be bent outwardly into the path of the appliance,
such as barbs at the base of a chain link fence.
Switching on and off
♦ To switch the appliance on, push the lock-off button (2),
and squeeze the trigger (1).
♦ To switch the appliance off, release the trigger.

Operating the trimmer (Fig. F, g–g3)
♦ With the unit on, angle unit and slowly swing the trimmer
side to side as shown in Figure G.
♦ Maintain a cutting angle of 5° to 10° as shown in Figure
G1. Do not exceed 10° (Figure G2). Cut with the tip of
the line. To keep distance from hard surfaces use edge
guide (7).
♦ Maintain a minimum distance of 600mm between the
guard and your feet as shown in Figure G3. To acheive
this distance adjust the overall height of the trimmer as
shown in Figure F.
Convert to edging mode (Fig. h, i)
Warning! When being used as an Edger, stones, pieces of
metal and other objects can be thrown out at high speed by
the line. The trimmer and guard are designed to reduce the
danger. However, MAKE SURE that other persons and pets
are at least 30 m away. Optimum cutting results are achieved
on edges deeper than 50 mm.
♦ Remove the battery from the trimmer.
♦ To operate as a maintenance edger, turn the collar (5) as
shown in part 1 of Figure H.
♦ Hold the metal shaft and rotate the lower housing 180°
as shown in part 2.
♦ Turn the collar until tight.
♦ Lift the edge guide (7) into the edging position as shown
in Figure I.
♦ Position the trimmer above the surface as shown in
Figure J.
♦ Return to the trimming position by loosening the lock
collar and rotating the lower housing back 180°. Turn the
collar until tight.
helpful cutting tips
♦ Use the tip of the string to do the cutting; do not force
string head into uncut grass. Use edge guide along
such things as fences, houses and flower beds for best
practices.
♦ Wire and picket fences cause extra string wear, even
breakage. Stone and brick walls, curbs, and wood may
wear string rapidly.
♦ Do not allow spool cap to drag on ground or other
surfaces.
♦ In long growth cut from the top down and do not exceed
300 mm high.
♦ Keep trimmer tilted toward the area being cut; this is the
best cutting area.
♦ The trimmer cuts when passing the unit from the right to
left. This will avoid throwing debris at the operator.
♦ Avoid trees and shrubs. Tree bark, wood moldings,
siding, and fence posts can easily be damaged by the
string.
