SECTION 3
MAINTENANCE
Figure 3- 1
- LUBRICATION
GENERAL
Blower efficiency and life depend on the quality of maintenance the blower receives. Maintenance must be done
regularly and with care. Clean work space, tools, solvents and wiping rags are necessary to avoid transferring dirt
into the unit. Scheduling regular maintenance of the blower will insure long trouble-free service.
LUBRICATION
Gears and bearings are splash lubricated by an oil slinger in each sump. Check the oil level in both sumps daily. Do
not operate the blower if the oil level is not in the middle of the sight gauge for each sump when the blower is not
running. An overfill or excess of oil can cause oil leaks.
DO NOT
OVERFILL OIL.
FILLING PROCEDURE
Refer to Figure 3-1.
While the blower is not running
remove the plug (B) from each sump. Add oil to each sump
until it reaches the
middle
of each oil level sight gauge (H). After adding oil wait for oil level to stabilize. Add or
remove oil to maintain oil level at middle of oil level sight gauge. Secure the plug (B) in each end.
LUBRICATION SERVICE
Add fresh oil as required to maintain proper level. The oil change period is governed by operating conditions such
as load, temperature, dirt, humidity, fumes and the quality of the oil used. Under severe operating conditions the oil
should be changed every 500 hours or more often. Under ideal operating conditions oil maybe used up to 4500 to
7500 hours. Change the oil often enough that it appears clean and clear when drained from the sump. The oil drain
plug is located at (A).
Gardner Denver blowers are shipped dry from the factory. Do not attempt to operate the blower
before following proper lubrication instructions. Permanent damage to the gears, bearings and
seals will occur.
Do not overfill oil as this will tend to cause excessive heating of the gears and may damage the
unit. An overfill of oil can cause oil leaks.
