Rotary hammers "diold": features and tips for use

Advice

• Do not try to drill a deep hole in hard material "one pass". First, you need to let the tool cool down, otherwise the electric drive may break down. Secondly, cleaning the hole from the generated waste by pulling the drill out of it at stops makes further drilling easier.
• Do not work in shock mode alone for long periods of time. Periodically switch to non-shock spin mode for at least a few minutes. This will cool the tool a little, and the lubricant inside it will redistribute and become more even.
• In order not to collide with a breakage of the chuck, avoid distortions of the punch during operation. The drill must be positioned strictly along the axis of the planned hole.
• To avoid unpleasant breakages and even injuries, use only consumables (drills, chucks, grease) approved by the tool manufacturer.
• The key to the long and reliable operation of the "Diold" rock drills is their timely maintenance and careful care. Dismantle the tool regularly, clean it from dirt, lubricate it in the places indicated in the instructions. The critical place of all rotary hammers is the electric motor, so it is imperative to inspect the condition of the brushes and the boot, if necessary, carry out preventive repairs or even replace them.

What is the disadvantage of a hammer drill?

The disadvantages of consumers include the following points:

• With daily use, in some cases, only two modes remain: rotational and shock-rotational. The third - "shock" - according to the owners, disappears. As a result, PRE-5 ceases to function in crushing mode.
• For some masters, after thirty minutes of continuous operation, PRE-5 often overheats. As a result, hammer drill owners say they often have to take ten-minute breaks. This is how much time is needed for PRE-5 to lower the temperature. As a result, the repair process using the equipment can take a long time.

Those who decided to purchase equipment should study how the reviews characterize the “Diold” tool, and the shortcomings noted by users must be taken into account. The characteristics obtained by PRE-5 allow us to conclude that the electrical product is intended only for domestic needs.
