Stopping The Machine; Oil Filter - WilTec JH95A Operation Manual

Application
1. Let the Jackhammer run at a low speed for the first 2-3 minutes after starting it in order to al-
low the machine to warm up.
2. Start utilising the device once the temperature is high enough (according to the required im-
pact energy) in order to achieve an ideal starting position and thereby reduce the strain placed
on the device and its parts.
Note:
When using the Jackhammer for the very first time, it should only be used at lower speeds for

the first 24 hours in order to extend its service life.
In order to achieve the best work results, it should be sufficient to operate the Jackhammer at

medium speed.

Stopping the machine

1. Let go of the acceleration switch and let the machine run in idle state for about 1-2 minutes.
2. Then halt the motor by pressing the red stop switch. (Figure 6)
Maintenance
Air filter
Regularly check the air filter. Accumulations of dust and dirt may block it and as a result reduce the ca-
pacities of the motor and damage the cylinder. In case of the filter being dirty, remove it and carefully
clean it with mild detergent and lukewarm water. Make sure that the air filter has dried completely be -
fore it is reinserted. If the air filter should show signs of wear or damage, repair it or replace it with a
new one. If working in especially dusty environments, the maintenance cycle has to be adjusted ac-
cordingly.

Oil filter

A clogged oil filter reduces the jackhammer's working speed as well as its power of impact and does
thereby not only affect its performance, but also increases the risk of the machine being damaged and
its operator being injured.
