Use and Care Guide
56-VOLT LITHIUM-ION CORDLESS 15" STRING TRIMMER—ST1520 & ST1520S22
◾
Wire and picket fences can cause extra string wear or breakage. Stone and brick
walls, curbs, and wood may wear strings rapidly.
◾
Avoid trees and shrubs. Tree bark, wood moldings, siding, and fence posts can
easily be damaged by the strings.
ADJUSTING CUTTING
LINE LENGTH
The trimmer head allows the operator to
release more cutting line without stopping
the motor. As line becomes frayed or worn,
additional line can be released by lightly
tapping the trimmer head on the ground
while operating the trimmer (Fig. 14).
WARNING:
Do not remove or alter
the line cutting blade assembly. Excessive line length will cause the motor to overheat
and may result in serious personal injury.
For best results, tap the trimmer head on bare ground or hard soil. If line release is
attempted in tall grass, the motor may overheat. Always keep the trimming line fully
extended. Line release becomes more difcult as the cutting line becomes shorter.
LINE REPLACEMENT
WARNING:
Never use metal-reinforced line, wire, or rope, etc. These can break
off and become dangerous projectiles.
WARNING:
Always use the recommended nylon cutting line with diameter no
more than 0.095 in. (2.4mm). Using line other than that specied may cause the string
trimmer to overheat or become damaged.
The string trimmer is equipped with an advanced auto-line winding system. The
cutting line can be wound onto the spool simply by pressing a single button. Loading
a full spool can usually be completed in 8 seconds. Avoid repeated operation of the
winding system in rapid succession to reduce the possibility of motor damage.
1. Remove the battery pack from the trimmer.
2. Cut one piece of cutting line 16 ft. (5m) long.
