1. General This is electric straight line type window wiper is to wiper off rain or splash of sea water on the front window glass of the steering house, etc. In order to maintain a clear view for safe navigation. This device is designed so that the wiper arm moves horizontally by converting unilateral rotary motion of the motor into linear reciprocal motion by means of the chain and the gear mechanism. 2. Components 2-1. Straight line type window wiper 1) Outside motor type (see fig. 1) (1) Motor unit (2) Casing (3) Arm and blade 2) Inside motor type (see fig. 2) (1) Motor unit (2) Casing (3) Arm and blade 2-2. Control box 2-3. Spare parts 1) Wiper blade (number in service) 2) Spring (number in service) 3) Lubricant (number in service) 4) Spare parts box (wooden) 3. Mechanism and Operation 3-1. Straight line type window wiper The main body consists of the motor, casing, and wiper arm with blade. 3-1-1. Motor unit (see fig. 1) The motor unit consists of the motor, reduction gear, and cable joiner box. The unit is weatherproof structure with the wiper cover and at the end of its output shaft is fitted a reduction gear. (for outside fitting type) AN electronically controlled induction motor with rated output of min. 120W is used to allow speed control. This unit is fitted to the wiper main body with four fitting bolts. - 2 -
3-1-2. Casings (see fig. 1) The casing portion is composed of the main body case, chain, carriage. In case of case, corrosion-resistant aluminum casting material KS A6061 is used. The case also served as a guide rail on which the carriage plate runs. The crank rod, which in centered on the four roller carriage plate, in fixed to one point in the chain-belt which extends between driving and driven pulleys. The crank rod converts the rotary on the chain-belt into reciprocal motion, which causes the carriage to move between the upper and lower guide rails reciprocally. This motion in transmitted via the arm head and the arm to the blade, which thus wiper off rain and sea water. 3-1-3. Wiper arm (see fig. 1) The wiper arm which consists of the arm head, arm and blade is mounted to extend down ward from the carriage. Synthetic rubber is fitted on the blade and spring is provided in the bent portion between the arm head and the arm so that the rubber contacts the glass evenly. Adjust the blade pressure with this spring, as the force applied to the glass surface changes depending on the relation between the wiper fitting surface and the window glass surface. 3-1-4. Heater (see fig. 1) During navigation in cold weather, ice often forms between the carriage and casing, making the use of the wiper impossible. Therefore a heater is provided to melt the ice in the casing. This heater is designed exclusively for the wiper and is not for window glass. Note that this heater is not effective when the bladed is stuck frozen to the window glass. WARNING 1) When ambient temperature is blow 0, turn on heater switch first to allow unit to warm up for at least ten(10) minutes before turning on window wiper switch. 2) Turn off heater switch after the unit in full operation. 3) Don't operate the unit idly for long time.3-1-5.

3-2. Control box - (Analog type) 1) POWER SWITCH This switch is used for electric power of main source ON/OFF. When select the off position, the operation is stopped after wiper is parking. 2) HEATER SWITCH The whole of wiper can be operased by operation. The heater is operated to intial statue automatically after one half hour. 3) LAMP Those brightness power and heater lamps are automatically operated by sensor in order to prepare at night and day. 4) SELECTOR SWITCH A) OFF : When this switch is set on the "OFF", wiper automatically return to the start position and stop wiping. B) INT. : This switch is device that wiper can be operated to intermitted speed. C) CONT. : This switch is device that wiper can be operated to various speed according to a speed switch. The rotating cycle is 16±5/min -> 32±5/min. 5) SPEED SWITCH This switch is device that is able to controller the wiping speed on INT. mode from 16±5/min -> 32±5/min. 6) INT. TIMER This switch is device that operate wiping time of wiper intermittently. The intermittent speed is controlled from 2 to 7 seconds. 7) MASTER SWITCH This switch is device that is able to move whole wiper at once. Just, wiper can not be moved at the state of "MASTER ON" individually, Push master switch once more and then push the individual switch, so that wiper can move individually. 8) INDIVIDUAL SWITCH This switch can operate each wiper individually. The individual wiping can be operated when the switch is just set but this switch can not use when master switch is "ON". WIPER CONTROL SERIES-803M - 8 -

5. Maintenance and checking replacement parts The window wiper is adjusted at the factory before delivery. As it is maintenance free, no maintenance or checking is needed by user. 5-1. Motor unit Redial ball bearing are used in the motor and reduction gears and they are completely sealed and greases. There is no need to supply oil or grease. It is becomes necessary to change motor units, loosen the four bolts fixing the unit and replace the entire unit with a new one. 5-2. Wiper arm and blade To replace the wiper arm, loosen the two bolts holding the arm head on the carr -age. The blade is fitted at the arm end with blade fitting screws. By pulling out these screws, blade, arm be easily changed. Note that blade are consumables and be sure to replace worn-out or "UNEVEN" rubber with new when ones necessary. BLADE HOLD BOLT1 NUT1 BOL2 NUT2 Separated BLADE BLADE CHANGE METHOD 1. Untie the locked nut(1) slackly. 2. Untie the locked nut(2). 3. After remove the blade from blade hold. 4. Changed the blade after Nut(1),(2) tighten. - 11 -
5-3. Chain The chain is integrated with the rod when replacing the chain the rod also. The rod can be removed easily by loosening the nut of the rod pin fixed on the carriage plate. Change method of chain 1 Dissemble the damaged Chain from sprocket. 2 Untie the Connected nut & bolt from the carriage and separate the chain from carriage. 3 Exchanged the chain on the carriage. 4 Connect the chain to the sprocket. 5-4. Heater unit The heater unit is constructed separately from the wiper body for replacement, remove the fitting bolts of the heater. The entire unit can be dismounted in the way. - 12 -
