7700 BATTERY OPERATION BATTERY OPERATION Machine is equipped with two (2) 200 amp hours, 48 volt battery packs put in parallel to create 400 amp hours. Batteries do not take a memory allowing recharge at any state. Do not over discharge. Over discharging could cause damage to batteries - 42 Volts REMOVING BATTERIES WARNING: Service work on batteries should only be done by a trained professional.
7700 BATTERY SAFE OPERATION DANGER - RISK OF EXPLOSIVE GASES: Chargers can ignite flammable materials and vapors. Do no use near fuels, grain, dust, solvents, or other flammables. Batteries generate explosive gases during normal operation. For this reason, to reduce the risk of battery explosion, it is important that each time, before using the charger, you read this manual a manufacturer of any equipment you intend to use in the vicinity of the batteries or battery charger.
When batteries have used their full life, they are recyclable at locations all over the US and Europe. Call National for recycle center. Batteries should only be maintained by certified National Technician. Batteries are lead acid constructions. If packs are allowed to reach temperatures above 125° F, ventilation can occur and discharge explosive gases (see warning label).
7700 BATTERY SAFE OPERATION WARNING: Do not put battery near fire. Must be recycled or disposed of properly. Do not touch terminals with metal objects. BATTERY DISPOSAL Battery must be recycled or disposed of in an environmentally sound manner. Do not place used batteries in regular trash. Do not expose the battery to fire or high heat as batteries may explode.
1. Battery Operation 2. Battery Storage The performance and life of a battery will vary with application useage, AGM batteries have a much longer shelf life than wet lead-acid batteries. temperature and depth of discharge AGM batteries tend to deliver higher With a self-discharge of only 1-3% per month, AGM batteries can be stored than their rated capacity (up to 10-15% higher) for 30 cycles until they for a year or longer without needing to be charged.
WARNING: Always find a safe place for recharging power packs with good ventilation away from sparks or flame sources and away from bystanders. Rope off if necessary. WARNING: Electrical shock hazard. Only use National’s approved charging system. WARNING: Disconnect from power source before operating. Failure to do so could cause damage to machine or bodily injury.
AC plug (a 240 volt model) have a qualified electrician install one. CAUTION: To reduce the risk of fire, observe the AC requirements located on the charger data label. Use circuits in accordance with the National Electric Code, ANSI/NFPA 70, and all local codes and ordinances.

7700 OPERATIONAL TIPS CASTER Keep clean and free of debris, make sure it can move freely. Clean as needed. Inspect before each use. Grease once a month. Moving a "weighted" machine only on the front caster and not on the cutting head or the Front Wheel Assembly can seem to make the machine turn sluggish.
7700 LOADING/UNLOADING • Always remove blade and cutting head when machine is being moved or transported • Cutting head and slide plate can be removed to make the machine more compact. • NEVER leave machine unattended on an incline. • Removing added weights help to make the machine easier and safer to move in and out of a vehicle. WARNING: Machine has a swivel front caster.
7700 LOADING/UNLOADING FORKLIFT CUPS There are two forklift cups mounted under the front of the machine (Figure A). Slide fork lift forks through forklift cups. Slide forks all the way back to touch the rear tire (Figure B). Before lifting machine, secure machine to fork lift with heavy 3000 lb / 1360 kgs.
7700 CENTER OF GRAVITY Be aware of your surroundings and machines operating angles. When changing from a low slide plate to a high slide plate setting or a low cutting head angle to a high cutting head angle, the operating “attitude” of the machine changes.
7700 JOB SITE MOVEMENT • Always remove blade and cutting head when machine is being moved or transported • Cutting head and slide plate can be removed to make the machine more compact. • NEVER leave machine unattended on an incline. •...
7700 JOB SITE MOVEMENT TO MOVE MACHINE WITHOUT POWER (PUSHING MACHINE) Forward: To move the machine forward, levers need to be pushed forward. To lock levers in place, connect a bungee-strap from each lever (pushing levers forward), pulling straps down to and connecting to the front plate (Figure A).
7700 WHEEL SIZES WHEEL SIZE The 18'' wheel comes standard on the machine. This wheel will work on all job types of application and heavy debris build-up (vct, ceramic etc.). It also works best for slippery/slimy residue, ie. double stick. Keep wheels clean and free of debris, make sure it can move freely.
7700 CUTTING HEAD & BLADES DIALING IN THE MACHINE Dialing in the machine is matching the correct cutting head, blade size, blade angle and added weight to the machine to make the material removal as easy as possible. For every material being removed, there is an optimum blade width, thickness, sharpness, angle and bevel (bevel up or bevel down).
7700 CUTTING HEAD & BLADES WEIGHT VS. SHARPNESS The most common way to compensate for a dull blade is to add more weight and raise the blade angle (see re-scrape setting). Weight allows dull blades to be used to a point. Weight also causes blades to dull and break easier.
7700 CUTTING HEAD & BLADES CUTTING HEAD INSERTION With machine off, insert desired cutting head into cutting head holder. Secure with cutting head clip. SHANK BLADE INSERTION Shank blades do not require a cutting head. Insert desired shank blade into cutting head holder. Secure with cutting head clip.
7700 BLADE APPLICATION/SET-UP CERAMIC SET-UP Slide plate should be set to lowest setting off the floor. Use a Shank Blade or a Shank Blade with a carbide tip. WOOD SET-UP Slide plate should be set to lowest setting off the floor. Use Shank Blades, Shank Blades with carbide tips or a 6"or 8"...
7700 BLADE APPLICATION/SET-UP RE-SCRAPING SET-UP Slide plate should be set to a higher setting off the floor. Use a Cutting Head from 8" to 27" with Scraper Blades to match cutting head size. A 15" scrapper blade would use a 14" Cutting Head. Razor Blades are faster but a Cutting Head from 8"...
7700 BLADE APPLICATION/SET-UP DITCHING CROSS ROOM DITCHING When removing hard to remove ceramic, Vct or vat, cross-room ditching will help to make the removal easier. Using a blade 2" to 6" in width, make ditches 1' to 2' apart in the same direction the machine will be removing the goods (Figure A).
7700 BLADES TYPES OF BLADES PREMIUM HIGH TEMPERED BLADES (.062) Works on all glued down carpets, VCT, VAT, rubber tile, cork, re-scraping adhesive, elastomeric coatings. Great for floor accumulations. Ultra high quality spring steel is extra hard for long blade life between sharpening.
7700 BLADES BLADE SHARPENING Dull blades greatly reduce cutting ability. Re-sharpen or replace as needed. In use, blades develop a back-bevel (Figure A). When re-sharpening, blade will not be truly sharp until all back-bevel is gone. Note: Thinner blades are easier to sharpen, but they also break easier. •...
