Macap CPS - Coffee Tamper - 52mm and 57.5mm

Adjustment:

With regular use of the machine, you might notice the lever's return force lessening. If this happens, make the adjustment as follows:

Loosen insert C by turning it anti-clockwise with a 3 mm hex key;
Using the same key, loosen insert B half a turn. At the same time, use a flathead screwdriver to apply pressure to voltage regulator A (to keep the internal screw from returning to its starting position);
Adjust the spring tension by turning voltage regulator A anti-clockwise to tighten the tension (clockwise to loosen it). Keep the adjustment slight to avoid a sudden or noisy return of the lever.
When the spring tension adjustment is complete, securely tighten insert B with the screwdriver.

Finally, screw down insert C tightly to ensure insert B doesn't loosen due to machine vibrations during use.

Maintenance:

With ongoing use, it's recommended to replace the O-rings, bulbs, and springs (sold separately) every 500,000 settings.
