GPS520 Assembly Instructions

Tame your overgrown lawn with the powerful SGS GPS520 strimmer.

Before diving into assembly, remember safety first! Keep the blade sheath on until it's securely attached, and find a spacious area for maneuvering to avoid accidents.

Here's a step-by-step guide to assembling your SGS GPS520 strimmer:

Handle Installation

Unscrew the top holding piece (A) with the 4 screws.

Position the handle with the throttle assembly slot closer to the main shaft (see image).

Reattach the holding piece and tighten the screws firmly using the larger hex key. Ensure the handle is secure and doesn't move.

Throttle Assembly

Remove the screw and nut at the throttle assembly base.

Slide it onto the handle. If it resists, gently rotate it left and right while pushing down.

Once aligned, refasten the screw and nut with the screwdriver provided.

Attaching the Guard

Unscrew the four fixing nuts on the guard.

Position the guard as shown in the image and tighten the screws/nuts to the appropriate setting for your chosen trimmer head (blade or line).

Remember, the guard sits closer for the blade and further away for the line trimmer head.

Installing the Cutting Attachments

a. Blade Attachment

Insert the smaller hex key into the side of the gear case and axle plate to prevent the axle from turning

Remove the axle nut (turn clockwise) and washers. Place the blade on the axle, followed by the axle washer and mount washer. Reattach the axle nut, tighten it counter-clockwise while holding the axle with the hex key. Now's a good time to remove the blade sheath.

Now's a good time to remove the blade sheath.

b. Line Trimmer Head

The spool screws directly onto the axle. Remove the washers and attach the spool by turning counter-clockwise.

Insert the smaller hex key into the side of the gear case and axle plate to prevent the axle from turning. Remove the axle nut (turn clockwise) and washers. Place the blade on the axle, followed by the axle washer and mount washer. Reattach the axle nut, tighten it counter-clockwise while holding the axle with the hex key. Now's a good time to remove the blade sheath.

Connecting the Shafts

Remove the rubber caps from both shafts.

Loosen the locking knob if needed. Press and hold the "Push" button while inserting the working shaft into the tube coupler.

Rotate gently to align the drive shafts, then release the button to lock them. Tighten the locking knob.

Harness and Balance

Don the harness and adjust for a snug fit. The hip guard should sit on the side of your hip/thigh, not the front. Slide it back and forth on the supporting band for optimal positioning.

Attach the strimmer to the harness and adjust it for a comfortable working position.

Fuel and Oil Mix

Important! Use only 2-Stroke Engine Oil for proper engine function. The wrong oil can damage or ruin the engine and void your warranty.

In the mixing jug, combine fuel and oil in a 40:1 ratio (40 parts fuel, 1 part oil). Add fuel first to the marking on the jug, then oil to the indicated level. Secure the cap and shake a few times.

Fuelling the Strimmer

Safety First! Ensure the engine is off and the strimmer is on bare ground.

Remove the fuel cap and carefully pour fuel through the smaller nozzle. If the tank is empty, you can use the entire contents of the mixing jug. This is also the maximum amount of fuel/oil mix to keep in the tank.

Starting the Strimmer

Press the priming bulb 5-8 times for easier starting.

Set the strimmer switch on the throttle assembly to "ON" (I).

For a cold start, move the choke to "Start" (closed) and squeeze the throttle trigger once.

Hold the engine steady and pull the starter cord firmly all the way. The engine should start after 3-5 pulls. Hold onto the starter cord handle! Don't let go and risk hitting the engine body. Let the cord recoil fully before pulling again. Once started, switch the choke to "Run" (Open).

Rev the engine 2-3 times and let it idle for 30-40 seconds. Your SGS GPS520 strimmer is now ready to tame your lawn!

Remember: Safety is paramount. Always wear gloves and eye protection while operating the strimmer. Now you can conquer your overgrown areas with confidence!
