Service and maintenance tasks to be conducted by qualified technicians / authorized repair centres only.
Service Schedule Table
1. For the convenience of transport the Pump is not supplied with oil, and the Breather Plug is not installed
(Certain models only). Please add 15W-30 - 10W-40 Machine oil before using. Pump oil is to be topped up the
centre line of the sight glass, then install the breather plug.
2. After first 20 hours use, remove the pump oil. Add a similar level of kerosene and operate the machine
without load for 10-15 seconds. Shut off the machine, drain of kerosene and replace with new motor oil.
3. Please check the oil mass before using. If lower than the centre line on the spy glass, top up to the centre
line.
4. Accumulative use after 100 hours, change the oil in the same way. For every 100 hours use thereafter, repeat
the oil change/service. It is very important in order to extend the service life of the pump.
