Frequently Asked Questions - MET4530 McGregor

How to fit the safety guard on the MET4530 grass trimmer?

Remove the mounting screw, attach the guard to the trimmer head by sliding into slots, then secure with the screw. Never operate without the guard.

How do I adjust the cutting angle for edging?

First adjust the shaft length for comfort. Then push the handle rotation locking button and rotate the main handle 90° or 180° depending on the mode. The trimmer head can also be adjusted to 30°-50° angle.

How to manually feed the cutting line?

Press and release the manual line feed button while gently pulling the lines until they reach the line cutter. If too much line extends, remove the spool cap and turn the spool anticlockwise.

What type of cutting line should I use?

Use only 1.65 mm diameter nylon line. Other sizes may not feed properly and can cause injury.

How do I replace the spool?

Remove the old spool, insert a new spool into the cutting head, feed one line through each eyelet, and refit the cap. Ensure lines are neat and not tangled.

Why does my trimmer stop intermittently?

Possible causes: damaged extension cord, internal wiring fault, or thermal overload. Check the cord first; if not, contact service agent. Always disconnect power before inspection.

How to clean and maintain the trimmer?

Unplug before cleaning. Wipe with a dry cloth; do not use water. Keep ventilation slots clean. No lubrication needed. Store in a dry place out of reach of children.

What does the clattering noise mean when starting?

The noise is normal when the line hits the line cutter. After about 5 seconds, the line is cut to correct length and noise reduces. If not heard, more line may be fed automatically.

How to store the grass trimmer?

Disconnect from power, clean it, and store in a dry place out of reach of children. Use cable storage hooks on the handle to keep the cord tidy.

What is the warranty period for the MET4530?

The product has a 2-year warranty from purchase date. It covers material and manufacturing defects but not misuse, commercial use, or consumable parts.

Operating instructions

WARNING: Always wear eye protection. Never lean over the trimmer head. Rocks or debris can ricochet or be thrown into eyes and face and cause blindness or other serious injury. When operating unit, check for the following:

Wear eye protection and heavy clothing. Hold front handle with one hand and auxiliary handle with the other hand. Keep unit below waist level. Work only from your right to your left to ensure debris is thrown away from you. Without bending over, keep line near and parallel to the ground (perpendicular when edging). Do not switch the machine on with the cutting head on or near material to be cut. Ensure the cutting line is at full speed before contacting material to be cut.

WARNING: MAKE SURE THAT LINE IS FED OUT BEFORE OPERATION. MAKE SURE MOTOR IS UP TO FULL SPEED BEFORE TRIMMING.

WARNING: Use only 1.65mm diameter cutting line. Other sizes of line will not feed properly and will result in improper cutting head function or can cause serious injury. Do not use other material such as wire, string, rope, etc. Wire can break off during cutting and become a dangerous missile that can cause serious injury.

1. TRIMMING

1) Keep the trimmer head at an angle of about 30^ to the ground when trimming (Fig J1).
2) Do not cut wet grass because it tends to stick to the trimmer head and guard, prevents proper discharge of grass clippings, and could cause you to slip and fall.
3) Regularly remove clippings and dirt around the trimmer head with a switched off trimmer.
4) Work rhythmically, stand firmly with your feet apart. Cut from right to left so the trimmings will be thrown away from the work area (Fig. J2).
5) When cutting longer /high grass, please make sure that you cut this down in 2 to 3 stages (Fig. J3, J4).
6) Do not move the trimmer too fast as this will result in ineffective cutting and possible damage.
If you find that the nylon line is too short follow the instruction as in "Automatic line feed system" or "To manually feed the line".

Operate

Operating instructions

3. AUTOMATIC LINE FEED SYSTEM

When initially switching on the trimmer, a small length of line is fed out.

A ‘clattering’ noise will be heard when the lines hit the line cutter. DO NOT BE ALARMED, this is quite normal. After about 5 seconds the line will be cut to the correct length and the noise will reduce as the motor receives full speed.

If the noise of the line being cut can't be heard, more line will be fed out.

To feed more line, it is first necessary to allow the trimmer to stop completely, then restart, allowing the motor to reach full speed.

Repeat above steps until you hear the lines hitting against the line cutter. (Do not repeat this procedure more than 6 times)

4. TO MANUALLY FEED THE LINE (SEE FIG. L)

If required, line can be fed out manually.

To operate, press and release manual line feed button, whilst gently pull out the lines until the lines reach the line cutter.

When the required amount of line is fed out, gently pull on the second line (there is no need to press the manual line feed button again)

If the line extends past the line cutter, too much line has been fed out.

If too much line is fed out, remove the spool cap and click spool anti-clockwise until the line is at the desired length.

5. TO REMOVE THE CAP

Press and hold in the two cap release latches. (See Fig. M)

Pull cap away from the spool holder.

Operating instructions

6. WHEN REFITTING THE SPOOL CAP.

Keep all areas of the cap and spool holder clean.

Refit the cap, pressing firmly down towards the spool holder to ensure cap is fully located.

Check that the cap is correctly fitted by trying to remove it without depressing the two latches.

7. TO REPLACE CUT LINE.

For your convenience it is recommended you buy spool and line complete.

--TO FIT SPOOL AND LINE COMPLETE:

1) Remove old spool.
2) Place new spool into cutting head. Release one line from cleat and feed line through eyelet.
3) Repeat for second line.
4) Refit the cap.

--TO FIT NYLON LINE ONLY:

WARNING!

Your trimmer is designed to use only line with a maximum diameter of 1.65

mm.

IMPORTANT - ALWAYS WIND THE LINE ONTO THE UPPER SECTION OF THE SPOOL FIRST.

1) Take two lines of approximately 3m (350W) / 5m (450W/600W) (Fig. N1).
2) Insert 15mm of line into one of the holes in the upper section of the spool and wind line in the direction of the arrows on the top of the spool (Fig. N2).
3) Leave approximately 100mm of line unwound and place into cleat (Fig. N3).
4) Repeat on lower section of spool with another line (Fig. N4).
5) Then fit spool as described in "TO FIT SPOOL AND LINE COMPLETE".

Care should be taken to ensure that the line is neatly coiled on the spool. Failure to do so will impair the efficiency of the automatic line feed.
