SELLING POINTS *As of August, 2009 researched by Hitachi (14.4 V Class Cordless Oil Pulse Driver) Lightweight and compact* The Hitachi Cordless Oil Pulse Driver (Model WP 14DSL) is superior to the competitive product of Company M in both weight and full length, and can be easily wired even in narrow places. Full length Maker Model Weight Full length HITACHI WP 14DSL 1.6 kg 169 mm HITACHI WP 12DM 1.9 kg 177 mm M 1.
Quiet: 75 dB While the impact mechanism of a conventional impact driver generates impact force by striking iron pieces for impact driving, an oil pulse driver generates high impact force by applying motor rotational force to an oil pulse section (in an oil pressure mechanism), thereby increasing oil pressure in the section and using this force for tightening screws. The oil pulse driver is much quieter than the impact driver since it does not strike iron pieces to generate force.
With a 2-stage switching function (rotational speed and number of impacts) With the changeover lever, you can change impact force in two modes. Use Save mode to tighten small-diameter wood screws or for driving screws into soft wood. Use Power mode to tighten large-diameter wood screws or for driving screws into hard wood. It is very convenient for you to change screwing force according to the purpose of work and work conditions.

PRECAUTIONS ON SALES PROMOTION 1. Safety Instructions In the interest of promoting the safest and most efficient use of the Model WP 14DSL Cordless Oil Pulse Driver by all our customers, it is very important when concluding a sale that the salesperson carefully ensure that the buyer seriously recognizes the importance of the Handling Instructions, and fully understands the precautions listed on the Caution Plate and Nameplate attached to each tool. A.
(8) Do not insert foreign objects into the air vents on the charger. The charger case is equipped with air vents to protect internal electronic components against overheating. Caution the customer not to drop or insert such foreign matter as metallic or flammable objects into the air vents. This could cause electrical shock, fire or other serious hazards. (9) Do not attempt to disassemble the storage battery or charger.
(2) The following cautions are listed on the Nameplate attached to each storage battery. [For Europe] CAUTION • Read thoroughly HANDLING INSTRUCTIONS before use. • Do not disassemble nor throw into fire. [For the USA and Canada] CAUTION • Read thoroughly HANDLING INSTRUCTIONS before use. • Do not disassemble nor throw into fire. (3) The following cautions are listed on the Nameplate attached to the Model UC 18YRSL Charger. [For the USA and Canada] • For safe operation, see instruction manual.
3. About Reduction in Tighten Torque (1) Battery voltage ------------------------------The tightening torque of the Pulse Driver is affected by battery voltage. The battery voltage gradually goes down as more screws are tightened. In particular, the battery voltage quickly drops just before activation of the over-voltage prevention circuit. This symptom is specific to cordless oil pulse drivers and impact drivers/wrenches.
REPAIR GUIDE WARNING: Always remove the battery from the main body before starting repair or maintenance work. Because the tool is cordless, leaving the battery inside and inadvertently activating the switch will start unexpected motor rotation, possibly resulting in serious injury. 1. Precautions on Disassembly and Reassembly The [Bold] numbers in the descriptions below correspond to item numbers in the Parts List and exploded view assembly diagram of the Model WP 14DSL. Disassembly 1.
2. Front Cap, Front Cover Insert the small flat-blade screwdriver between the Front Cap [5] and Front Cover [6], and then remove both from Hammer Case [7]. 3. Hook Remove Truss Hd. Screw M4 (Black) [38] and Hook [37]. You can conduct disassembly work without removing Hook [37]. This would help simplify later disassembly work. 4. Carbon Brush Remove the two Brush Caps [32] of the left and right Carbon Brushes 5 x 6 x 11.5 [31]. Remove each Carbon Brush 5 x 6 x 11.
