Failure to observe these operating instructions can cause product or property damage or personal injury. Flender does not accept any liability for damage or operating failures which are due to non- adherence to these operating instructions. The gear unit described in these instructions reflects the state of technical development at the time these operating instructions went to print.
The quality of the oil used must meet the requirements of the operating instructions BA 7300, which is provided as a separate item, otherwise the warranty provided by Flender will be void. Flender urgently recommends using one of the oils listed in BA 7300, all of which have been appropriately tested and meet the requirements.
Page 13
Flender recommends regular inspection to ascertain whether the selected lubricating oil is still approved by Flender. If it is not, another brand of oil should be selected instead. Assembly and operating instructions A5033en...
In order to safeguard plants, systems, machines and networks against cyber threats it is necessary to implement (and continually maintain) a holistic industrial security concept that corresponds to the current state of the art. Flender products and solutions undergo continuous development in this respect.

Safety instructions 2.6 Correct use in hazardous zones (explosive atmospheres) • In the case of gear units that are operated in combination with electrical machines that generate current or through which current flows (e.g. motors and generators), take measures to ensure that no current can flow through the gear unit. Current flowing through the gear unit can result in irreparable damage to rolling-contact bearings and gearing.
It can essentially be operated in both directions of rotation. Gear units equipped with backstop or overrunning clutch are the exceptions in this case. Flender must be consulted if, for these versions, the direction of rotation is to be reversed. Type B3.E is equipped with an axial fan, and can only be operated in one direction.

Description 3.7 Backstop Principle of operation The backstop is fitted with centrifugally-operated sprags. If the gear unit rotates in the specified direction, the inner ring rotates together with the sprag cage in the direction of rotation of the shaft, while the outer ring remains stationary. Above a certain speed (disengagement speed) the sprags disengage from the outer ring.
3.8 Torque limiting backstop (special version) The blocking direction of the backstop can be changed by turning over the cage. You must always contact Flender in advance if you wish to change the blocking direction. NOTICE Damage to the backstop and gear unit due incorrect direction of rotation Damage to the backstop and gear unit due incorrect direction of rotation possible.
You can change the blocking direction of the backstop by turning over the cage. You must always contact Flender in advance if you wish to change the blocking direction. NOTICE Damage to the backstop and gear unit due incorrect direction of rotation Damage to the backstop and gear unit due incorrect direction of rotation possible.
It is not permissible that dimension "x “ specified on the backstop type plate is fallen below. min. Flender must be contacted once this dimension is reached. WARNING Risk of injury as a result of moving system parts There is a risk that after the motor is switched off the load cannot be securely kept in position, and that it can accelerate in the reverse direction.
Description 3.9 Cooling 3.9.1 Principle of operation Generally, the fan is mounted on the high-speed shaft of the gear unit and is protected from accidental contact using an air guide cover.
