Check oil Level:

Before using the compressor check the oil level 
using the dipstick. If the oil is not up to the mark it
 should  be topped up with 

Jefferson HT68 

Compressor oil (

see 

Fig.3

). 

Sight glass / Oil Level: 

The compressor oil level can be viewed through the
sight glass; the compressor must be on a level 
surface to measure the oil level through the sight
glass accurately (see 

Fig.4

):

• 

The top of the red dot indicates the full mark

• 

The bottom of the red dot indicates the low mark  

Important:

 Always ensure that the oil level is correct before operating the compressor.

Ensure working environment is suitable for use: 

This compressor must be used on a flat, level surface The maximum safe operating angle 
in any direction is 10° degrees (see 

Fig.5)

.

• 

Do not operate the compressor on inclines in excess of 10° degrees. 

• 

Serious damage to pump components may result from insufficient lubrication.

• 

Never use the air compressor on a rooftop or elevated position that could allow the  
unit to fall or be tipped over.

• 

Use additional air hose for elevated jobs.

Check power supply is correct for this compressor:

It is essential that the air compressor has an adequate power supply.  Always utilize more air hose 
before choosing to use an extension lead, as low voltage could cause damage to the motor. (Low 
voltage damage is not covered under warranty).  Read and understand all the electrical safety 
guidelines laid out in this manual, follow all applicable local authority safety guidelines.
