Maintenance
PLANETARY GEARBOX LUBRICATION
The oil reservoir shown in Fig. 3 is constructed using an acrylic body. This is a very durable
material, which is able to withstand severe impact, without sustaining damage. However, if a
reservoir is damaged, it must be replaced with an approved reservoir, or components,
recommended by the manufacturer. If a reservoir sustains any damage, call your PENTA TMR
dealer immediately.
The reservoirs have decals on them, showing the maximum and minimum fluid levels, under
operating conditions. At no time is the fluid to be lower than the minimum recommended level, as
damage to a gearbox may occur. If the fluid is higher than the maximum level, the oil may
overflow the reservoir, and cause fluid loss, (if the mixer is level the level in the reservoir will stay
more stable.)
The Gearbox on your PENTA TMR MIXER uses synthetic oil as its lubricant. It does not matter
the brand of oil, only that specifications need to be 80-140 / Full Synthetic / GL5 Rating the oil
reservoir located on the right side of the stand frame on your mixer contains the lubricant for the
gearbox. There are maximum and minimum oil level decals on your reservoir. (See Fig.2). It is
important that the oil level in the reservoir remains between the maximum and minimum oil levels,
as indicated. If it is too low, the gearbox will not be sufficiently lubricated. If it is above the
maximum level, spillage will occur. The oil in the gearbox may expand and contact due to
temperature changes, whether from operating the mixer or changes in ambient temperature. It is
recommended to check the oil level in the reservoirs every 8 hours of operation.
Breather Cap
The oil reservoir has a filter/breather located on the top, which must be attached to the reservoir at
all times. This breather is removable, to allow filling of the reservoir. If the filter/breather
becomes contaminated, remove the breather, and clean it using a mils detergent. This breather can
be separated into 3 sections, for complete cleaning. If the breather is damaged or needs replacing,
contact your PENTA TMR dealer. If any commodities are dumped on the reservoir, it should be
cleaned immediately, and the breather checked, to ensure that the air can freely pass through it. (If
ever spraying water to clean the mixer, protect the breather and reservoir). If it is plugged, clean
properly, as outlined above.
