  2. Turn on the engine, return the throttle lever to the lowest speed position, and put the harness hook to the hanging part of the machine.

  3. Adjust the length of the harness so that the blade may be parallel to the ground in the working position. In order to prevent slack during operation, turn up to ensure the extra length of the band and not loose.

CUTTING OPERATION

Stahlmann MS520 - CUTTING OPERATION - 1

METAL BLADE USAGE

Always cut by guiding the head from your right to left.
A metal blade cut best up to the point 1/3 from the edge. Use that area for cutting shrubs, tough and thick weeds. For cutting young grass, you can use up to 2/3 from the tip of blade.
Adjust the engine speed according to the cutting objects. Cut the young grass at middle speed, and cut shrubs or tough and thick weeds of high speed.

(1) For branches and trees
(2) For grass and weeds
(3) Direction of cutting
(4) Direction of rotation

IMPORTANT

Operating at low speed makes it easier for grass, weeds, or twigs to become caught up in the blades, and also it makes the shaft and clutch wear down more quickly.

NYLON CUTTER USAGE

Nylon cord consumes large power, please note that the engine rotation speed in operation should be 50% as large as when using metal blade.
Nylon cutter cut grass with the power of cord rotation. If you try to cut grass for the length of cord at one time, rotation speed becomes lower due to resistance and you cannot cut well. In case of large resistance, get the nylon cutter away from grass once, make the rotation speed higher, and cut a small amount of grass at one time.
If you try to cut grass by swinging the grass trimmer in the reverse way (from left to right), scraps fly in the direction away from the body. You can avoid getting your clothes dirty.

8. MAINTENANCE

Stahlmann MS520 - MAINTENANCE - 1

BLADE

Sharpen each cutting edge and make sure the bottom corner is rounded. (F11)
Do not cool the blade with water in case of using grinder. It may cause cracks on blade.

AFTER 25 HOURS OF

Stahlmann MS520 - AFTER 25 HOURS OF - 1

AIR CLEANER

Check and clean the filter element in warm, soapy water as required. Dry completely before installing. If the element is broken or shrunk, replace with a new one. (F12)

(1) Cover
(2) Clamp
(3) Element
(4) Screen
(5) Body

IMPORTANT

A clogged air filter may increase fuel consumption while cutting down the engine power.

Operating the grass trimmer without the air filter or with a deformed filter element will quickly ruin the engine.

FUEL FILTER

Take the filter out of the fueling port using a small wire hook. Disconnect the filter assembly from the fuel pipe and unhook the retainer to disassemble it. Clean the components with gasoline.

IMPORTANT

A clogged fuel filter may cause poor acceleration of the engine.

Stahlmann MS520 - IMPORTANT - 1

SPARK PLUG

Remove and inspect the spark plug and clean the electrodes as necessary with brush.

The spark gap should be adjusted to 0.6 0.7mm (F13)

INTAKE AIR COOLING VENT

Heck the intake air-cooling vent and the area around the cylinder cooling fins, and remove any waste, which has attached itself to the grass trimmer.

IMPORTANT

Note that failing to do so could cause the muffler to become overheated, and that this in turn could cause the grass trimmer to overheat.

Stahlmann MS520 - IMPORTANT - 1

GEAR CASE

Supply multi-purpose grease at every 25 hours of use. Remove the cutter holders to arrange for old grease to exit. (F14)

AFTER 25 HOURS OF

■ MUFFLER

  1. Remove the muffler, insert a screwdriver into the vent, and wipe away any carbon buildup. Wipe away any carbon buildup on the muffler exhaust vent at the same time.
  2. Tighten all screws, bolts, and fittings.
  3. Check to see if any oil or grease has worked its way in between the clutch lining, and if it has wiped it away using oil-free, lead-free gasoline.
  4. Remove the float cabin of the carburetor and clean the inside.

ADJUSTING CARBURETOR
