5.1 INTENDED USE
The gear reducer is designed for use in industrial machines. Please refer to our catalogue or our web page for the maximum
permitted torques and speeds. The most important maximum permitted values are indicated on the nameplate of the product.
But the whole data can be found on our product catalogues. Using the product out of the product catalogue / nameplate's per-
mitted ranges will cancel the warranty/manufacturer declaration and Dana Motion Systems Italia S.r.l. will not take any respon-
sibility.
The gear units are intended for industrial machines and may only be used in accordance with the information provided in this
manual the product catalogue and the nameplate of the gearbox. They comply with the applicable standards and regulations
and meet the requirements of the directive 2006/42/EC. The gearbox must be started up, maintained and operated according
this manual. The gearbox most be incorporated with 2006/42/EC confirming parts/machines.
5.2 IMPROPER USE
The operation of the gear reducer is prohibited if:
• It was not mounted/installed according to regulations and this manual
• The gear reducer is very soiled
• It is operated without lubricant
• It is operated out of the permitted values provided on catalogues and/or nameplate.
NOTE:
A motor connected to the gear unit is only allowed to be operated in the frequency entries so that the data provided on
nameplate/catalogue of the gear unit is not exceeded and is accordance with the nameplate/catalogue. The speed
range will be provided on the name plate if Dana Motion Systems Italia S.r.l. is informed that the gear unit will be used
with frequency inverter. If not informed the nameplate will have a single fixed speed and only this speed is allowed.
The electric motor and frequency inverter must be in accordance with 2006/42/EC.
NOTE:
If the gear units input is used with variable speed gear unit, this must be informed to Dana Motion Systems Italia S.r.l.
before ordering and on the nameplate the allowed maximum and minimum speeds (speed range) will be provided. If not
mentioned by ordering the gear units speed will be a fixed single input speed and only this speed is allowed.
NOTE:
If the gear unit will be driven by belt / coupling / chain drive etc. the gear unit is only allowed to be used according the
nameplate/catalogue entries. Different speed, higher motor power, higher radial/axial loads etc. than nameplate/cata-
logue is not allowed.
NOTE:
The ambient temperature must be between +5 - +40 ºC and no abrasive media must attack the paint and seals. If differ-
ent working conditions this must be informed to Dana Motion Systems Italia S.r.l. before ordering.
The gearbox maintenance (oil change / check ) must be done according this manual.
NOTE:
Every usage which exceeds the limits stated above, the nameplate and catalogue of the product (especially higher
torques and speeds) is not compliant with the regulations, and thus prohibited.

5.3.1.4 Lubricant
5.3.1.5 Ambient Conditions
5.4 TIGHTENING TORQUES
All screwed connections for which a tightening torque is specified, must on principle be tightened with a calibrated torque
wrench and checked. Use the following torques for the threaded bores over the gear unit housing. For connecting elements
refer to the mechanical installation part.
Table 3:
WARNING
Extended, intensive contact with oils can lead to skin irritations.
Avoid extended contact with oil, and clean oil off skin thoroughly.
WARNING
Hot oil can cause scalding.
When changing oil, protect yourself against contacting hot oil.
DANGER
If the gear unit will be used in outdoor applications the gear unit must be prevented from rain snow and dust. Entering sub-
stances inside the gear unit from seals can damage the gear unit. Observe the safety instructions for outdoor use
EN12100:2010.
WARNING
Standard gearboxes are allowed to work in ambient temperatures between +5 to +40ºC unless differently specified on the
nameplate. Using the gear unit out of this range can cause damage to the gear unit or environment. Over +40 ºC ambient
conditions the gear unit surface temp could be so high causing burns when touched.

6 THINKS TO CHECK BEFORE THE GEAR UNIT OR GEARED MOTOR IS INSTAL-
LED
Before you install the gearbox you have to be sure that the gearbox is arrived with the all necessary equipment and without
damage. Points to take into consideration before you start to install the unit;
• You have received the correct operation manual of the your product.
• The gearbox and all its parts are transported without damage.
• The gearbox is stored correctly according the instructions in this manual
• You have the latest product catalogue or you have access to our web page
6.1 TRANSPORTATION
When the goods arrive, first check for any damage. If some damage observed, immediately contact the transport company and
inform about the damage. Contact Dana Motion Systems Italia S.r.l. for the damage and do not start to install the unit until it is
agreed that the damage has no affect of operation.
NOTE:
If geared motors are used, please also refer to the manual of the motor manufacturer.
DANGER
Falling or hard placement can damage the gear unit.
Only use hoisting and securing equipment which is permitted for the size / weight of your gear unit. Ensure that the load is
slowly and carefully handled and placed.
DANGER
Use the supplied eyebolts or lifting holes for lifting up the gear unit. The eyebolts are capable to carry the weight of
gearboxes only. Do not hang additional loads. Use suitable hoisting equipment which is capable to hold the gear
units weight. Refer to the catalogue for various types weights. See drawing bellow for hoisting point.
DANGER
Do not stay beneath / under the lifting/hoisting equipment which may cause serious injuries by falling down objects, accidental
movements, unexpected accidents.

THINKS TO CHECK BEFORE THE GEAR UNIT OR GEARED MO-
Dana Incorporated IMM-0020EN - Installation and Maintenance Manual
6.2 STORAGE
If the geared unit or geared motor will be stored up to 3 years refer to the following instructions;
With Packing;
Use corrosion protection oil for the output shaft and connection surfaces like flange surface or foot assembling surface. Seal
the unit in a plastic wrap and pack it in container. A moisture indicator should be placed around the container to observe the
moisture. Relative atmospheric humidity should not exceed 50%. The container should be kept under roof which protects from
snow and rain. Under this condition the gear unit can be stored up to 3 year with regular check. The ambient temperature should
be between -5 to 60 ºC.
Without Packing;
Use protection oil for the output shaft and connection surfaces like flange surface or foot assembling surface. If no packing is
used and the gearbox is stored without packing, the ambient temperature should be between 5 to 60 ºC. The gearbox must be
kept under enclosed roof with constant temperature and constant humidity not exceeding 50%. The storage should be free of
dust and dirt and ventilated with filter. If the gearbox is stored without packing it is recommended not to store more than 2 years
and regular check during this time is recommended.
If stored in open protect against insect damage.
